1 Corinthians 11:
13 Judge in yourselves: is it comely that a woman pray unto God uncovered?
14 Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him?
15 But if a woman have long hair, it is a glory to her: for her hair is given her for a covering.
16 But if any man seem to be contentious, we have no such custom, neither the churches of God.
1 Cor.11:13-16
