21 Tell me, you who want to be under the law, do you not understand what the law says? 22 For it is written that Abraham had two sons, one by the slave woman and the other by the free woman.4:22 See Genesis 16:15 and Genesis 21:2–3. 23 His son by the slave woman was born according to the flesh, but his son by the free woman was born through the promise.
24 These things serve as illustrations, for the women represent two covenants. One covenant is from Mount Sinai and bears children into slavery: This is Hagar. 25 Now Hagar stands for Mount Sinai in Arabia and corresponds to the present-day Jerusalem, because she is in slavery with her children. 26 But the Jerusalem above is free, and she is our mother.
