'Birth' in the Bible

We being Jews by birth, and not sinners of the Gentiles,

My children, of whom I am again in birth-pains till Christ is formed in you,

Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.

Which things have a secret sense; because these women are the two agreements; one from the mountain of Sinai, giving birth to servants, which is Hagar.

For it is in the Writings, You who have never given birth, be glad; give cries of joy, you who have had no birth-pains; for the children of her who has been given up by her husband are more than those of the woman who has a husband.

But as in those days he who had birth after the flesh was cruel to him who had birth after the Spirit, even so it is now.
