'Head Covered' in the Bible

Any man who keeps his head covered, when praying or preaching in public, dishonors him who is his Head;

Indeed, if a woman does not keep her head covered, she may as well cut her hair short. But, since to cut her hair short, or shave it off, marks her as one of the shameless women, let her keep her head covered.

A man ought not to have his head covered, for he has been from the beginning 'the likeness of God' and the reflection of his glory, but woman is the reflection of man's glory.
