19 God said, “No, but gSarah your wife shall bear you a son, and you shall call his name hIsaac. 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.”
