16 So I have become your enemy in speaking the truth to you?
17 They are not rightly zealous after you, but desire to shut you out from us, that ye may be zealous after them.
18 But it is right to be zealous at all times in what is right, and not only when I am present with you--
19 my children, of whom I again travail in birth until Christ shall have been formed in you:
20 and I should wish to be present with you now, and change my voice, for I am perplexed as to you.
21 Tell me, ye who are desirous of being under law, do ye not listen to the law?
22 For it is written that Abraham had two sons; one of the maid servant, and one of the free woman.
