19 To this God said: “Your wife Sarah will definitely bear you a son, and you must name him Isaac.*+ And I will establish my covenant with him for an everlasting covenant to his offspring* after him.+

3 “‘In time I took your forefather Abraham+ from the other side of the River* and had him walk through all the land of Caʹnaan and made his offspring* many.+ I gave him Isaac;+

7 Neither are they all children because they are Abraham’s offspring;+ rather, “What will be called your offspring will be through Isaac.”+
