Old Testament

The Book of Exodus: Chapter 28:31-43

"You shall make the robe of the ephod all of blue. There shall be an opening for his head in the middle of it; it shall have a woven binding all around its opening, like the opening in a coat of mail, so that it does not tear.

"And upon its hem you shall make pomegranates of blue, purple, and scarlet, all around its hem, and bells of gold between them all around:
a golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe all around. And it shall be upon Aaron when he ministers, and its sound will be heard when he goes into the holy place before the Lord and when he comes out, that he may not die.

"You shall also make a plate of pure gold and engrave on it, like the engraving of a signet: HOLINESS TO THE LORD.
And you shall put it on a blue cord, that it may be on the turban; it shall be on the front of the turban. So it shall be on Aaron's forehead, that Aaron may bear the iniquity of the holy things which the children of Israel hallow in all their holy gifts; and it shall always be on his forehead, that they may be accepted before the Lord.

"You shall skillfully weave the tunic of fine linen thread, you shall make the turban of fine linen, and you shall make the sash of woven work.

"For Aaron's sons you shall make tunics, and you shall make sashes for them. And you shall make hats for them, for glory and beauty. So you shall put them on Aaron your brother and on his sons with him. You shall anoint them, consecrate them, and sanctify them, that they may minister to Me as priests. And you shall make for them linen trousers to cover their nakedness; they shall reach from the waist to the thighs. They shall be on Aaron and on his sons when they come into the tabernacle of meeting, or when they come near the altar to minister in the holy place, that they do not incur iniquity and die. It shall be a statute forever to him and his descendants after him.

New Testament

The First Epistle of Paul the Apostle to the Corinthians: Chapter 11:1-16

Imitate me, just as I also imitate Christ.

Now I praise you, brethren, that you remember me in all things and keep the traditions just as I delivered them to you. But I want you to know that the head of every man is Christ, the head of woman is man, and the head of Christ is God. Every man praying or prophesying, having his head covered, dishonors his head. But every woman who prays or prophesies with her head uncovered dishonors her head, for that is one and the same as if her head were shaved. For if a woman is not covered, let her also be shorn. But if it is shameful for a woman to be shorn or shaved, let her be covered. For a man indeed ought not to cover his head, since he is the image and glory of God; but woman is the glory of man. For man is not from woman, but woman from man. Nor was man created for the woman, but woman for the man. For this reason the woman ought to have a symbol of authority on her head, because of the angels.

Nevertheless, neither is man independent of woman, nor woman independent of man, in the Lord. For as woman came from man, even so man also comes through woman; but all things are from God. Judge among yourselves. Is it proper for a woman to pray to God with her head uncovered? Does not even nature itself teach you that if a man has long hair, it is a dishonor to him? But if a woman has long hair, it is a glory to her; for her hair is given to her for a covering. But if anyone seems to be contentious, we have no such custom, nor do the churches of God.
