I Corinthians 11:12-16

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.
