Genesis 17:18-21 And Abraham said unto God, O that Ishmael might live before thee! And God said: Sarah thy wife shall bear thee a son indeed; and thou shall call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. As for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. BUT MY COVENANT WILL I ESTABLISH WITH ISAAC, which Sarah shall bear unto thee at this set time in the next year.What is this covenant God made with Abraham and through the seed of Isaac? Could it be a land covenant?
