Established the Covenant with Isaac, not Ishmael
<p><b>Genesis 17:18-21 (ESV) </b>
<sup>18 </sup> And Abraham said to God, “Oh that Ishmael might live before you!”
<sup>19 </sup> God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.
<sup>20 </sup> As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and multiply him greatly. He shall father twelve princes, and I will make him into a great nation.
<sup>21 </sup> But I will establish my covenant with Isaac, whom Sarah shall bear to you at this time next year.”</p>
