19Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name [u:e2ffe6e3ef]Isaac; I will establish My covenant with him for an everlasting covenant[/u:e2ffe6e3ef], and with his descendants after him. 20[u:e2ffe6e3ef]And as for Ishmael[/u:e2ffe6e3ef], I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He shall beget twelve princes, and [u:e2ffe6e3ef]I will make him a great nation. 21[b:e2ffe6e3ef]But[/b:e2ffe6e3ef] My covenant I will establish with Isaac[/u:e2ffe6e3ef], whom Sarah shall bear to you at this set time next year." 22Then He finished talking with him, and God went up from Abraham.
Ishmael received the sign of the covenant. But God says that Ishmael was not part of the covenant!
Can a person receive the sign of the covenant without being in the covenant?
