Hagar and Sarah Represent Two Covenants

²¹ Tell me, you who are wanting to be under the law, do you not understand^[a] the law? ²² For it is written that Abraham had two sons, one by the female slave and one by the free woman. ²³ But the one by the female slave was born according to human descent, and the one by the free woman through the promise, ²⁴ which things are spoken allegorically, for these women are two covenants, one from Mount Sinai, bearing children for slavery, who is Hagar. ²⁵ Now Hagar is Mount Sinai in Arabia, and corresponds to the present Jerusalem, for she is a slave with her children. ²⁶ But the Jerusalem above is free, which is our mother. ²⁷ For it is written,

²⁸ But you, brothers, are children of the promise, just as Isaac. ²⁹ But just as at that time the child born according to human descent persecuted the child born according to the Spirit, so also now. ³⁰ But what does the scripture say? “Drive out the female slave and her son, for the son of the female slave will never inherit with the son”^[c] of the free woman. ³¹ Therefore, brothers, we are not children of the female slave but of the free woman.
