Galatians 4:19-24
English Standard Version
Chapter 4
19my little children, for whom I am again in the anguish of childbirth until Christ is formed in you! 20I wish I could be present with you now and change my tone, for I am perplexed about you.
21Tell me, you who desire to be under the law, do you not listen to the law?
22For it is written that Abraham had two sons, one by a slave woman and one by a free woman.
23But the son of the slave was born according to the flesh, while the son of the free woman was born through promise.
24Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar.
