“However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise.”
Galatians 4:23 (WEB)
Context Reading
21Tell me, you that desire to be under the law, don’t you listen to the law? 22For it is written that Abraham had two sons, one by the servant, and one by the free woman. 23However, the son by the servant was born according to the flesh, but the son by the free woman was born through promise. 24These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar. 25For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.
