18 And Abraham said to God, "If only Ishmael might live under your blessing!" 19 Then God said, "Yes, but your wife Sarah will bear you a son, and you will call him Isaac.[1] I will establish my covenant with him as an everlasting covenant for his descendants after him. 20 And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation.
18 And Abraham said unto God, O that Ishmael might live before thee! 19 And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20 And 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.
18 And Abraham said to God, "Oh that Ishmael might live before you!" 19 God said, "No, but Sarah your wife shall bear you a son, and you shall call his name Isaac.
18 Recovering, Abraham said to God, "Oh, keep Ishmael alive and well before you!" 19 But God said, "That's not what I mean. Your wife, Sarah, will have a baby, a son. Name him Isaac (Laughter). I'll establish my covenant with him and his descendants, a covenant that lasts forever. 20 "And Ishmael? Yes, I heard your prayer for him. I'll also bless him; I'll make sure he has plenty of children - a huge family. He'll father twelve princes; I'll make him a great nation.
18 And Abraham said to God, "Oh, that Ishmael might live before You!" 19 Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him. 20 And as for Ishmael, 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 I will make him a great nation.
18 So Abraham said to God, "May Ishmael live under your special blessing!" 19 But God replied, "No-Sarah, your wife, will give birth to a son for you. You will name him Isaac, and I will confirm my covenant with him and his descendants as an everlasting covenant. 20 As for Ishmael, I will bless him also, just as you have asked. I will make him extremely fruitful and multiply his descendants. He will become the father of twelve princes, and I will make him a great nation.

Commentary on Genesis 17:15-22
(Read Genesis 17:15-22)
Here is the promise made to Abraham of a son by Sarai, in whom the promise made to him should be fulfilled. The assurance of this promise was the change of Sarai's name into Sarah. Sarai signifies my princess, as if her honour were confined to one family only; Sarah signifies a princess. The more favours God confers upon us, the more low we should be in our own eyes. Abraham showed great joy; he laughed, it was a laughter of delight, not of distrust. Now it was that Abraham rejoiced to see Christ's day; now he saw it and was glad, John 8:56. Abraham, dreading lest Ishmael should be abandoned and forsaken of God, put up a petition on his behalf. God gives us leave in prayer to be particular in making known our requests. Whatever is our care and fear, should be spread before God in prayer. It is the duty of parents to pray for their children, and the great thing we should desire is, that they may be kept in covenant with Him, and may have grace to walk before him in uprightness. Common blessings are secured to Ishmael. Outward good things are often given to those children of godly parents who are born after the flesh, for their parents' sake. Covenant blessings are reserved for Isaac, and appropriated to him.
