Genesis 21:3

¹⁹God said, “No, but Sarah, your wife, will bear you a son. You shall call his name Isaac.^[+] I will establish my covenant with him for an everlasting covenant for his offspring after him.

⁷Neither, because they are Abraham’s offspring, are they all children. But, “your offspring will be accounted as from Isaac.”

⁶Sarah said, “God has made me laugh. Everyone who hears will laugh with me.”

^18[+] to whom it was said, “Your offspring will be accounted as from Isaac,”

¹²God said to Abraham, “Don’t let it be grievous in your sight because of the boy, and because of your servant. In all that Sarah says to you, listen to her voice. For your offspring will be named through Isaac.

³I took your father Abraham from beyond the River, and led him throughout all the land of Canaan, and multiplied his offspring,^[+] and gave him Isaac.

²Abraham became the father of Isaac. Isaac became the father of Jacob. Jacob became the father of Judah and his brothers.

²He said, “Now take your son, your only son, Isaac, whom you love, and go into the land of Moriah. Offer him there as a burnt offering on one of the mountains which I will tell you of.”

⁸He gave him the covenant of circumcision. So Abraham became the father of Isaac, and circumcised him the eighth day. Isaac became the father of Jacob, and Jacob became the father of the twelve patriarchs.
