1 Corinthians 11:15-19

but if a woman has long hair, it is a glory to her? For her hair is given to her as a covering.

But if anyone is inclined to be contentious, we have no such practice, nor have the churches of God.

Now in giving this next instruction I do not praise you, because you come together not for the better, but for the worse.

For, in the first place, when you come together as a church, I hear that divisions exist among you; and in part I believe it.

For there also have to be factions among you, so that those who are approved may become evident among you.
