Galatians 4:22 For it is written, that Abraham had two sons; the one by a bond-maid, the other by a free-woman. (WBS YLT)

Galatians 4:23 But he who was of the bond-woman, was born according to the flesh; but he of the free-woman was by promise. (WBS YLT)

Galatians 4:26 and the Jerusalem above is the free-woman, which is mother of us all, (YLT)

Galatians 4:30 Nevertheless, what saith the scripture? Cast out the bond-woman and her son: for the son of the bond-woman shall not be heir with the son of the free-woman. (WBS YLT)
