1 Corinthians 11:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ Any man who prays or prophesies with something on his head disgraces his head, ⁵ but any woman who prays or prophesies with her head unveiled disgraces her head—it is one and the same thing as having her head shaved. 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 have her hair cut off or to be shaved, she should wear a veil.
