1 Corinthians 11:4-6

11:4 Any man who prays or prophesies with his head covered disgraces his head. 11:5 But any woman who prays or prophesies with her head uncovered disgraces her head, for it is one and the same thing as having a shaved head. 11:6 For if a woman will not cover her head, she should cut off her hair. But if it is disgraceful for a woman to have her hair cut off or her head shaved, she should cover her head.
