Galatians 4:23-25

Amplified Bible

²³ But the child of the slave woman was born according to the flesh and had an ordinary birth, while the son of the free woman was born in fulfillment of the promise. ²⁴ Now these facts are about to be used [by me] as an allegory [that is, I will illustrate by using them]: for these women can represent two covenants: one [covenant originated] from Mount Sinai [where the Law was given] that bears children [destined] for slavery; she is Hagar. ²⁵ Now Hagar is (represents) Mount Sinai in Arabia and she corresponds to the present Jerusalem, for she is in slavery with her children.
