Galatians 4:21-23

New Revised Standard Version, Anglicised Catholic Edition

The Allegory of Hagar and Sarah

²¹ Tell me, you who desire to be subject to the law, will you not listen to the law? ²² For it is written that Abraham had two sons, one by a slave woman and the other by a free woman. ²³ One, the child of the slave, was born according to the flesh; the other, the child of the free woman, was born through the promise.
