19 God said, “No, but ^gSarah your wife shall bear you a son, and you shall call his name ^hIsaac.¹ I will establish my covenant with him as an everlasting covenant for his offspring after him.

21 But ^lI will establish my covenant with Isaac, ^mwhom Sarah shall bear to you at this time next year.”

2 And Sarah ^mconceived and bore Abraham a son in his old age ⁿat the time of which God had spoken to him.

9 For this is what the promise said: ^r“About this time next year I will return, and Sarah shall have a son.”
