Galatians 4:21-23 Holman Christian Standard Bible (HCSB)
Sarah and Hagar: Two Covenants
21 Tell me, those of you who want to be under the law, don’t you hear the law? 22 For it is written that Abraham had two sons, one by a slave and the other by a free woman. 23 But the one by the slave was born according to the impulse of the flesh, while the one by the free woman was born as the result of a promise.
