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)
Leviticus 19:20 And whoever lieth carnally with a woman that is a bond-maid betrothed to a husband, and not at all redeemed, nor freedom given her; she shall be scourged: they shall not be put to death, because she was not free. (WBS)
