And for the "off topic" issue: Gen 22:18 "and in your seed {singular} shall all the nations of the earth be blessed, because you have obeyed my voice." This, I believe, is Paul's reference in Gal. 3:16. Which only serves to show how the whole story of Abraham is a unit. All of it hangs together, and forms a "covenant-context" in which these things are interpreted.
