1 Corinthians 11:3-6

But there is one thing I want you to know: The head of every man is Christ, the head of woman is man, and the head of Christ is God. A man dishonors his head if he covers his head while praying or prophesying. But a woman dishonors her head if she prays or prophesies without a covering on her head, for this is the same as shaving her head. Yes, if she refuses to wear a head covering, she should cut off all her hair! But since it is shameful for a woman to have her hair cut or her head shaved, she should wear a covering.
