Galatians 4:21-28 New King James Version (NKJV)

Two Covenants

²¹ Tell me, you who desire to be under the law, do you not hear the law? ²² For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. ²³ But he who was of the bondwoman was born according to the flesh, and he of the freewoman through promise, ²⁴ which things are symbolic. For these are ^[a]the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar— ²⁵ for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children— ²⁶ but the Jerusalem above is free, which is the mother of us all. ²⁷ For it is written:

²⁸ Now we, brethren, as Isaac was, are children of promise.
