1 Corinthians 11:4-6

Revised Standard Version Catholic Edition

⁴ Any man who prays or prophesies with his head covered dishonors his head, ⁵ but any woman who prays or prophesies with her head unveiled dishonors her head—it is the same as if her head were shaven. ⁶ For if a woman will not veil herself, then she should cut off her hair; but if it is disgraceful for a woman to be shorn or shaven, let her wear a veil.
