Two Mothers, Two Covenants: Galatians 4:21-31

Tell me, you who want to be under the law, are you not aware of what the law says?

Paul turned to allegory. The Galatians wanted the law? Then let them listen to what the law actually said. Let them hear the story of Abraham's household—and understand which son they resembled.

For it is written that Abraham had two sons, one by the slave woman and one by the free woman.

Two sons. Both Abraham's. Both circumcised. Both raised in the patriarch's tent.
