New International Version
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)
