The Birth of Isaac

21 Now the Lord was gracious to Sarah^(A) as he had said, and the Lord did for Sarah what he had promised.^{(B) 2} Sarah became pregnant and bore a son^(C) to Abraham in his old age,^(D) at the very time God had promised him.^{(E) 3} Abraham gave the name Isaac^[a](F) to the son Sarah bore him. ⁴ When his son Isaac was eight days old, Abraham circumcised him,^(G) as God commanded him. ⁵ Abraham was a hundred years old^(H) when his son Isaac was born to him.

⁶ Sarah said, “God has brought me laughter,^(I) and everyone who hears about this will laugh with me.” ⁷ And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”^(J)

Hagar and Ishmael Sent Away

⁸ The child grew and was weaned,^(K) and on the day Isaac was weaned Abraham held a great feast. ⁹ But Sarah saw that the son whom Hagar the Egyptian had borne to Abraham^(L) was mocking,^{(M) 10} and she said to Abraham, “Get rid of that slave woman^(N) and her son, for that woman’s son will never share in the inheritance with my son Isaac.”^(O)

¹¹ The matter distressed Abraham greatly because it concerned his son.^{(P) 12} But God said to him, “Do not be so distressed about the boy and your slave woman. Listen to whatever Sarah tells you, because it is through Isaac that your offspring^[b] will be reckoned.^{(Q) 13} I will make the son of the slave into a nation^(R) also, because he is your offspring.”

²² For it is written that Abraham had two sons, one by the slave woman^(A) and the other by the free woman.^{(B) 23} His son by the slave woman was born according to the flesh,^(C) but his son by the free woman was born as the result of a divine promise.^(D)

²⁴ These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. ²⁵ Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. ²⁶ But the Jerusalem that is above^(E) is free, and she is our mother. ²⁷ For it is written:

²⁸ Now you, brothers and sisters, like Isaac, are children of promise.^{(G) 29} At that time the son born according to the flesh^(H) persecuted the son born by the power of the Spirit.^(I) It is the same now. ³⁰ But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.”^{[b](J) 31} Therefore, brothers and sisters, we are not children of the slave woman,^(K) but of the free woman.^(L)
