1 Corinthians 11:14

Overview - 1 Corinthians 11
1	He reproves them, because in holy assemblies,
4	their men prayed with their heads covered,
6	and women with their heads uncovered;
17	and because generally their meetings were not for the better, but for the worse;
21	as, namely, in profaning with their own feast the Lord's supper.
25	Lastly, he calls them to the first institution thereof.

1 Corinthians 11:14  (King James Version)
Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him?
