(Mark 6:21‑22)). Numerous religious feasts (Ex. 12:1616And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you. (Exodus 12:16); Lev. 23:21-2421And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations. 22And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God. 23And the Lord spake unto Moses, saying, 24Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation. (Leviticus 23:21‑24); Jude 1212These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots; (Jude 12)).

“Sacrifice” From Boyd’s Bible Dictionary:

(making sacred). Propitiatory, atoning or thanksgiving offering to God. An ordained rite (Lev. 17:4-94And bringeth it not unto the door of the tabernacle of the congregation, to offer an offering unto the Lord before the tabernacle of the Lord; blood shall be imputed unto that man; he hath shed blood; and that man shall be cut off from among his people: 5To the end that the children of Israel may bring their sacrifices, which they offer in the open field, even that they may bring them unto the Lord, unto the door of the tabernacle of the congregation, unto the priest, and offer them for peace offerings unto the Lord. 6And the priest shall sprinkle the blood upon the altar of the Lord at the door of the tabernacle of the congregation, and burn the fat for a sweet savor unto the Lord. 7And they shall no more offer their sacrifices unto devils, after whom they have gone a whoring. This shall be a statute for ever unto them throughout their generations. 8And thou shalt say unto them, Whatsoever man there be of the house of Israel, or of the strangers which sojourn among you, that offereth a burnt offering or sacrifice, 9And bringeth it not unto the door of the tabernacle of the congregation, to offer it unto the Lord; even that man shall be cut off from among his people. (Leviticus 17:4‑9); Deut. 16:5-195Thou mayest not sacrifice the passover within any of thy gates, which the Lord thy God giveth thee: 6But at the place which the Lord thy God shall choose to place his name in, there thou shalt sacrifice the passover at even, at the going down of the sun, at the season that thou camest forth out of Egypt. 7And thou shalt roast and eat it in the place which the Lord thy God shall choose: and thou shalt turn in the morning, and go unto thy tents. 8Six days thou shalt eat unleavened bread: and on the seventh day shall be a solemn assembly to the Lord thy God: thou shalt do no work therein. 9Seven weeks shalt thou number unto thee: begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn. 10And thou shalt keep the feast of weeks unto the Lord thy God with a tribute of a freewill offering of thine hand, which thou shalt give unto the Lord thy God, according as the Lord thy God hath blessed thee: 11And thou shalt rejoice before the Lord thy God, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates, and the stranger, and the fatherless, and the widow, that are among you, in the place which the Lord thy God hath chosen to place his name there. 12And thou shalt remember that thou wast a bondman in Egypt: and thou shalt observe and do these statutes. 13Thou shalt observe the feast of tabernacles seven days, after that thou hast gathered in thy corn and thy wine: 14And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite, the stranger, and the fatherless, and the widow, that are within thy gates. 15Seven days shalt thou keep a solemn feast unto the Lord thy God in the place which the Lord shall choose: because the Lord thy God shall bless thee in all thine increase, and in all the works of thine hands, therefore thou shalt surely rejoice. 16Three times in a year shall all thy males appear before the Lord thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the Lord empty: 17Every man shall give as he is able, according to the blessing of the Lord thy God which he hath given thee. 18Judges and officers shalt thou make thee in all thy gates, which the Lord thy God giveth thee, throughout thy tribes: and they shall judge the people with just judgment. 19Thou shalt not wrest judgment; thou shalt not respect persons, neither take a gift: for a gift doth blind the eyes of the wise, and pervert the words of the righteous. (Deuteronomy 16:5‑19)). Sacrificial offerings numerous; but chiefly, the “burnt-offering” (Lev. 1:1-171And the Lord called unto Moses, and spake unto him out of the tabernacle of the congregation, saying, 2Speak unto the children of Israel, and say unto them, If any man of you bring an offering unto the Lord, ye shall bring your offering of the cattle, even of the herd, and of the flock. 3If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the Lord. 4And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him. 5And he shall kill the bullock before the Lord: and the priests, Aaron's sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation. 6And he shall flay the burnt offering, and cut it into his pieces. 7And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire: 8And the priests, Aaron's sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar: 9But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savor unto the Lord. 10And if his offering be of the flocks, namely, of the sheep, or of the goats, for a burnt sacrifice; he shall bring it a male without blemish. 11And he shall kill it on the side of the altar northward before the Lord: and the priests, Aaron's sons, shall sprinkle his blood round about upon the altar. 12And he shall cut it into his pieces, with his head and his fat: and the priest shall lay them in order on the wood that is on the fire which is upon the altar: 13But he shall wash the inwards and the legs with water: and the priest shall bring it all, and burn it upon the altar: it is a burnt sacrifice, an offering made by fire, of a sweet savor unto the Lord. 14And if the burnt sacrifice for his offering to the Lord be of fowls, then he shall bring his offering of turtledoves, or of young pigeons. 15And the priest shall bring it unto the altar, and wring off his head, and burn it on the altar; and the blood thereof shall be wrung out at the side of the altar: 16And he shall pluck away his crop with his feathers, and cast it beside the altar on the east part, by the place of the ashes: 17And he shall cleave it with the wings thereof, but shall not divide it asunder: and the priest shall burn it upon the altar, upon the wood that is upon the fire: it is a burnt sacrifice, an offering made by fire, of a sweet savor unto the Lord. (Leviticus 1:1‑17)); “sin-offering,” and “trespass-offering” (Lev. 7:1-101Likewise this is the law of the trespass offering: it is most holy. 2In the place where they kill the burnt offering shall they kill the trespass offering: and the blood thereof shall he sprinkle round about upon the altar. 3And he shall offer of it all the fat thereof; the rump, and the fat that covereth the inwards, 4And the two kidneys, and the fat that is on them, which is by the flanks, and the caul that is above the liver, with the kidneys, it shall he take away: 5And the priest shall burn them upon the altar for an offering made by fire unto the Lord: it is a trespass offering. 6Every male among the priests shall eat thereof: it shall be eaten in the holy place: it is most holy. 7As the sin offering is, so is the trespass offering: there is one law for them: the priest that maketh atonement therewith shall have it. 8And the priest that offereth any man's burnt offering, even the priest shall have to himself the skin of the burnt offering which he hath offered. 9And all the meat offering that is baken in the oven, and all that is dressed in the fryingpan, and in the pan, shall be the priest's that offereth it. 10And every meat offering, mingled with oil, and dry, shall all the sons of Aaron have, one as much as another. (Leviticus 7:1‑10)); “peace-offering” (Lev. 7:11-3411And this is the law of the sacrifice of peace offerings, which he shall offer unto the Lord. 12If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and cakes mingled with oil, of fine flour, fried. 13Besides the cakes, he shall offer for his offering leavened bread with the sacrifice of thanksgiving of his peace offerings. 14And of it he shall offer one out of the whole oblation for an heave offering unto the Lord, and it shall be the priest's that sprinkleth the blood of the peace offerings. 15And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning. 16But if the sacrifice of his offering be a vow, or a voluntary offering, it shall be eaten the same day that he offereth his sacrifice: and on the morrow also the remainder of it shall be eaten: 17But the remainder of the flesh of the sacrifice on the third day shall be burnt with fire. 18And if any of the flesh of the sacrifice of his peace offerings be eaten at all on the third day, it shall not be accepted, neither shall it be imputed unto him that offereth it: it shall be an abomination, and the soul that eateth of it shall bear his iniquity. 19And the flesh that toucheth any unclean thing shall not be eaten; it shall be burnt with fire: and as for the flesh, all that be clean shall eat thereof. 20But the soul that eateth of the flesh of the sacrifice of peace offerings, that pertain unto the Lord, having his uncleanness upon him, even that soul shall be cut off from his people. 21Moreover the soul that shall touch any unclean thing, as the uncleanness of man, or any unclean beast, or any abominable unclean thing, and eat of the flesh of the sacrifice of peace offerings, which pertain unto the Lord, even that soul shall be cut off from his people. 22And the Lord spake unto Moses, saying, 23Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat. 24And the fat of the beast that dieth of itself, and the fat of that which is torn with beasts, may be used in any other use: but ye shall in no wise eat of it. 25For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the Lord, even the soul that eateth it shall be cut off from his people. 26Moreover ye shall eat no manner of blood, whether it be of fowl or of beast, in any of your dwellings. 27Whatsoever soul it be that eateth any manner of blood, even that soul shall be cut off from his people. 28And the Lord spake unto Moses, saying, 29Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace offerings unto the Lord shall bring his oblation unto the Lord of the sacrifice of his peace offerings. 30His own hands shall bring the offerings of the Lord made by fire, the fat with the breast, it shall he bring, that the breast may be waved for a wave offering before the Lord. 31And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'. 32And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings. 33He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for his part. 34For the wave breast and the heave shoulder have I taken of the children of Israel from off the sacrifices of their peace offerings, and have given them unto Aaron the priest and unto his sons by a statute for ever from among the children of Israel. (Leviticus 7:11‑34)); the latter also a “free-will” offering. These offerings could not satisfy God’s holy requirements for removing sin, but they were required of all under the law, until Christ’s sacrifice of Himself, which can and did once and for all put away sin for the believer (Heb. 9-10).

“Feasts” From Concise Bible Dictionary:

The feasts of Jehovah, as instituted under the law as given by Moses, partake more of the character of commemorations, or assemblies. of the congregation to celebrate special dealings of the Lord, and consequently special seasons—in the history of His people, being called “holy convocations.” A list of the yearly feasts is given in Leviticus 23. The first mentioned is the Sabbath, and if this is counted as one, by considering the Passover and the feast of unleavened bread as one there are seven in all—the perfect number. If the Sabbath is not included, as that was a weekly festival, being the rest of God, and on which the others were founded, then the Passover and the feast of unleavened bread may be counted as two, and still there are seven. There can be no doubt that these seven feasts were typical of the ways of blessing from the cross to the millennium. They stand thus:

Tisri 15th Feast of Tabernacles: ingathering of the vintage. (Lev. 23:33-4433And the Lord spake unto Moses, saying, 34Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the Lord. 35On the first day shall be an holy convocation: ye shall do no servile work therein. 36Seven days ye shall offer an offering made by fire unto the Lord: on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the Lord: it is a solemn assembly; and ye shall do no servile work therein. 37These are the feasts of the Lord, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the Lord, a burnt offering, and a meat offering, a sacrifice, and drink offerings, every thing upon his day: 38Beside the sabbaths of the Lord, and beside your gifts, and beside all your vows, and beside all your freewill offerings, which ye give unto the Lord. 39Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the Lord seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath. 40And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the Lord your God seven days. 41And ye shall keep it a feast unto the Lord seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month. 42Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths: 43That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the Lord your God. 44And Moses declared unto the children of Israel the feasts of the Lord. (Leviticus 23:33‑44))
These seven are called “the set feasts” (Num. 29:3939These things ye shall do unto the Lord in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings. (Numbers 29:39); 1 Chron. 23. 31; 2 Chron. 31:33He appointed also the king's portion of his substance for the burnt offerings, to wit, for the morning and evening burnt offerings, and the burnt offerings for the sabbaths, and for the new moons, and for the set feasts, as it is written in the law of the Lord. (2 Chronicles 31:3); Neh. 10:3333For the showbread, and for the continual meat offering, and for the continual burnt offering, of the sabbaths, of the new moons, for the set feasts, and for the holy things, and for the sin offerings to make an atonement for Israel, and for all the work of the house of our God. (Nehemiah 10:33)). Also “holy convocations,” when the people assembled together to offer the various offerings, and thus be reminded of their association with the living God, to whom they owed all their blessings. To ensure this at least thrice in the year, it was enjoined that all the males should appear before the Lord three times in the year, and they must not appear empty. These times were at the Feast of Unleavened Bread (no doubt including the Passover); the Feast of Weeks, or of Harvest; and the Feast of Tabernacles, or “of Ingathering” (Ex. 23:14-1714Three times thou shalt keep a feast unto me in the year. 15Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:) 16And the feast of harvest, the firstfruits of thy labors, which thou hast sown in the field: and the feast of ingathering, which is in the end of the year, when thou hast gathered in thy labors out of the field. 17Three times in the year all thy males shall appear before the Lord God. (Exodus 23:14‑17); Deut. 16:1616Three times in a year shall all thy males appear before the Lord thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the Lord empty: (Deuteronomy 16:16)). See PASSOVER, &c.

“Sacrifice” From Concise Bible Dictionary:

As a technical religious term “sacrifice” designates anything which, having been devoted to a holy purpose, cannot be called back. In the generality of sacrifices offered to God under the law the consciousness is supposed in the offerer that death, as God’s judgment, was on him; hence the sacrifice had to be killed that it might be accepted of God at his hand. In fact the word sacrifice often refers to the act of killing.
The first sacrifice we read of was that offered by Abel, though there is an indication of the death of victims in the fact that Adam and Eve were clothed by God with coats of skins. Doubtless in some way God had instructed man that, the penalty of the fall and of his own sin being that his life was forfeited, he could only appropriately approach God by the death of a substitute not chargeable with his offense; for it was by faith that Abel offered unto God a more excellent sacrifice than Cain (Heb. 11:44By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh. (Hebrews 11:4)). God afterward instructed Cain that if he did not well, sin, or a sin offering, lay at the door.
The subject was more fully explained under the law: “The life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul” (Lev. 17:1111For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul. (Leviticus 17:11)). Not that the blood of bulls and of goats had any inherent efficacy to take away sins; but it was typical of the blood of Christ which is the witness that they have been taken away for the believer by Christ’s sacrifice.
Christ appeared once in the end of the world “to put away sin by the sacrifice of himself;” and He having once died, there remains no more sacrifice for sins (Eph. 5:22And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savor. (Ephesians 5:2); Heb. 9:2626For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. (Hebrews 9:26); Heb. 10:4,12,264For it is not possible that the blood of bulls and of goats should take away sins. (Hebrews 10:4)
12But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; (Hebrews 10:12)
26For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, (Hebrews 10:26)
). Without faith in the sacrificial death of Christ there is no salvation, as is taught in Romans 3:2525Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; (Romans 3:25); Romans 4:24-2524But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; 25Who was delivered for our offences, and was raised again for our justification. (Romans 4:24‑25) and 1 Corinthians 15:1-41Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4And that he was buried, and that he rose again the third day according to the scriptures: (1 Corinthians 15:1‑4).
