Galatians 4:22-24

King James Version

²² For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.

²³ But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.

²⁴ Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
