18But it is good to have an interest in a good cause at all times, and not only when I am present with you.
19My children, of whom I am again in birth-pains till Christ is formed in you,
20Truly my desire is to be present with you now, using a changed voice; for I am troubled about you.
21Say, you whose desire it is to be under the law, do you not give ear to the law?
22Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.
23Now 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.
24Which 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.
