Galatians 4:21 DBY

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.

²³  But he [that was] of the maid servant was born according to flesh, and he [that was] of the free woman through the promise.
