“Weave” From Boyd’s Bible Dictionary:

Most ancient nations knew the art of weaving
The Egyptians were skilled weavers (Gen. 41:4242And Pharaoh took off his ring from his hand, and put it upon Joseph's hand, and arrayed him in vestures of fine linen, and put a gold chain about his neck; (Genesis 41:42)). That the Hebrews brought the art along with them from bondage is clear from the fabrics manufactured in the wilderness: goat-hair covers, linen curtains (Ex. 26:1-131Moreover thou shalt make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubims of cunning work shalt thou make them. 2The length of one curtain shall be eight and twenty cubits, and the breadth of one curtain four cubits: and every one of the curtains shall have one measure. 3The five curtains shall be coupled together one to another; and other five curtains shall be coupled one to another. 4And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the uttermost edge of another curtain, in the coupling of the second. 5Fifty loops shalt thou make in the one curtain, and fifty loops shalt thou make in the edge of the curtain that is in the coupling of the second; that the loops may take hold one of another. 6And thou shalt make fifty taches of gold, and couple the curtains together with the taches: and it shall be one tabernacle. 7And thou shalt make curtains of goats' hair to be a covering upon the tabernacle: eleven curtains shalt thou make. 8The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits: and the eleven curtains shall be all of one measure. 9And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double the sixth curtain in the forefront of the tabernacle. 10And thou shalt make fifty loops on the edge of the one curtain that is outmost in the coupling, and fifty loops in the edge of the curtain which coupleth the second. 11And thou shalt make fifty taches of brass, and put the taches into the loops, and couple the tent together, that it may be one. 12And the remnant that remaineth of the curtains of the tent, the half curtain that remaineth, shall hang over the backside of the tabernacle. 13And a cubit on the one side, and a cubit on the other side of that which remaineth in the length of the curtains of the tent, it shall hang over the sides of the tabernacle on this side and on that side, to cover it. (Exodus 26:1‑13)); embroidered raiment (Ex. 28:4,394And these are the garments which they shall make; a breastplate, and an ephod, and a robe, and a broidered coat, a mitre, and a girdle: and they shall make holy garments for Aaron thy brother, and his sons, that he may minister unto me in the priest's office. (Exodus 28:4)
39And thou shalt embroider the coat of fine linen, and thou shalt make the mitre of fine linen, and thou shalt make the girdle of needlework. (Exodus 28:39)); woolen garments (Lev. 13:4747The garment also that the plague of leprosy is in, whether it be a woollen garment, or a linen garment; (Leviticus 13:47)). Though the loom is not mentioned, its various parts are, as the shuttle, beam (1 Sam. 17:77And the staff of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron: and one bearing a shield went before him. (1 Samuel 17:7); 2 Kings 23:77And he brake down the houses of the sodomites, that were by the house of the Lord, where the women wove hangings for the grove. (2 Kings 23:7); 1 Chron. 4:2121The sons of Shelah the son of Judah were, Er the father of Lecah, and Laadah the father of Mareshah, and the families of the house of them that wrought fine linen, of the house of Ashbea, (1 Chronicles 4:21); Job 7:66My days are swifter than a weaver's shuttle, and are spent without hope. (Job 7:6); Prov. 31:13,2413She seeketh wool, and flax, and worketh willingly with her hands. (Proverbs 31:13)
24She maketh fine linen, and selleth it; and delivereth girdles unto the merchant. (Proverbs 31:24); Isa. 38:1212Mine age is departed, and is removed from me as a shepherd's tent: I have cut off like a weaver my life: he will cut me off with pining sickness: from day even to night wilt thou make an end of me. (Isaiah 38:12)).

“Weaver, Weaving” From Concise Bible Dictionary:

This art was early practiced in Egypt, and though the looms were of the simplest description, some Egyptian productions were very fine. Weaving was known to the Israelites, and by it they produced fine work for the tabernacle and the priests’ robes. A weaver’s beam is often referred to as a heavy thing for a man to use as a weapon (Ex. 28:3232And there shall be an hole in the top of it, in the midst thereof: it shall have a binding of woven work round about the hole of it, as it were the hole of an habergeon, that it be not rent. (Exodus 28:32); Ex. 35:3535Them hath he filled with wisdom of heart, to work all manner of work, of the engraver, and of the cunning workman, and of the embroiderer, in blue, and in purple, in scarlet, and in fine linen, and of the weaver, even of them that do any work, and of those that devise cunning work. (Exodus 35:35); Ex. 39:22,2722And he made the robe of the ephod of woven work, all of blue. (Exodus 39:22)
27And they made coats of fine linen of woven work for Aaron, and for his sons, (Exodus 39:27); 1 Sam. 17:77And the staff of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron: and one bearing a shield went before him. (1 Samuel 17:7); Job 7:66My days are swifter than a weaver's shuttle, and are spent without hope. (Job 7:6), etc). Of the wicked it is said, they “weave the spider’s web.... their webs shall not become garments” (Isa. 59:5-65They hatch cockatrice' eggs, and weave the spider's web: he that eateth of their eggs dieth, and that which is crushed breaketh out into a viper. 6Their webs shall not become garments, neither shall they cover themselves with their works: their works are works of iniquity, and the act of violence is in their hands. (Isaiah 59:5‑6)).
