1 Corinthians 11
7For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man.
8For the man is not of the woman: but the woman of the man.
9Neither was the man created for the woman; but the woman for the man.
10
For this cause ought the woman to have power on her head
because of the angels.
11Nevertheless neither is the man without the woman, neither the woman without the man, in the Lord.
12For as the woman is of the man, even so is the man also by the woman; but all things of God.
What does the "for this cause" mean? What is it referring to?
