“Seven” From Boyd’s Bible Dictionary:
A favorite, and often symbolic, number among Hebrews
(Gen. 2:2; 7:2; 41:2-32And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. (Genesis 2:2)
2Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female. (Genesis 7:2)
2And, behold, there came up out of the river seven well favored kine and fatfleshed; and they fed in a meadow. 3And, behold, seven other kine came up after them out of the river, ill favored and leanfleshed; and stood by the other kine upon the brink of the river. (Genesis 41:2‑3)). Used as a round number (1 Sam. 2:55They that were full have hired out themselves for bread; and they that were hungry ceased: so that the barren hath born seven; and she that hath many children is waxed feeble. (1 Samuel 2:5); Matt. 12:4545Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation. (Matthew 12:45)). Type of abundance and completeness (Gen. 4:15,2415And the Lord said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the Lord set a mark upon Cain, lest any finding him should kill him. (Genesis 4:15)
24If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold. (Genesis 4:24); Matt. 18:21-2221Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? 22Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven. (Matthew 18:21‑22)). These references, and other places, show a seventh day and seventh year sabbath and a seven times seventh year of Jubilee; also sacrificial animals limited to seven, and the golden candlesticks. Seven priests with seven trumpets surrounded Jericho for seven days, and seven times on the seventh day. In the Apocalypse we find seven churches, seven candlesticks, seven stars, seven seals, seven trumpets, seven vials, seven plagues, seven angels.
“Week” From Boyd’s Bible Dictionary:
The division of time into weeks of seven days each dates from the earliest historic times among many and wide-apart nations
The Hebrew week began on our Sunday, their Sabbath being the seventh day or Saturday. The only day of their week they named was the Sabbath. The rest ran by numbers, as first, second, third, and so forth. Besides their week of days, Hebrews had their week of years, every seven years, and their week of seven times seven years, or year of jubilee, every fiftieth year (Gen. 8:10; 29:2710And he stayed yet other seven days; and again he sent forth the dove out of the ark; (Genesis 8:10)
27Fulfil her week, and we will give thee this also for the service which thou shalt serve with me yet seven other years. (Genesis 29:27)). The “feast of weeks” corresponded with Pentecost (Ex. 23:15; 34:2215Thou 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:) (Exodus 23:15)
22And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year's end. (Exodus 34:22); Lev. 23:15-2215And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete: 16Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the Lord. 17Ye shall bring out of your habitations two wave loaves of two tenth deals: they shall be of fine flour; they shall be baken with leaven; they are the firstfruits unto the Lord. 18And ye shall offer with the bread seven lambs without blemish of the first year, and one young bullock, and two rams: they shall be for a burnt offering unto the Lord, with their meat offering, and their drink offerings, even an offering made by fire, of sweet savor unto the Lord. 19Then ye shall sacrifice one kid of the goats for a sin offering, and two lambs of the first year for a sacrifice of peace offerings. 20And the priest shall wave them with the bread of the firstfruits for a wave offering before the Lord, with the two lambs: they shall be holy to the Lord for the priest. 21And 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. (Leviticus 23:15‑22); Num. 28).
