Bible: Galatians 4:21-23
An Appeal from Allegory
4:21 Tell me, you who want to be under the law, do you not understand the law? 1 4:22 For it is written that Abraham had two sons, one by the 2 slave woman and the other by the free woman. 4:23 But one, the son by the slave woman, was born by natural descent, 3 while the other, the son by the free woman, was born through the promise.
