18 It is good to be always zealous to do good, and not only when I am present with you.
19 My little children, of whom I travail in birth again until Christ is formed in you,
20 I desire to be present with you now and to change my voice, for I stand in doubt of you.
21 Tell me, ye that desire to be under the law, have ye not heard the law?
22 For it is written that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
23 But he who was of the bondwoman was born according to the flesh, but he of the freewoman was born through the promise.
24 Which things are an allegory; for these women are the two covenants: the one from the Mount Sinai, which begat unto slavery, which is Hagar.
