Galatians 4:22-24

American Standard Version

²² For it is written, ^[a]that Abraham had two sons, one by the handmaid, and one by the freewoman. ^23 [b]Howbeit the son by the handmaid is born after the flesh; but the son by the freewoman is born through promise. ²⁴ Which things contain an allegory: for these women are two covenants; one from mount Sinai, bearing children unto bondage, which is Hagar.
