Genesis 17:18 WEB

¹⁶  I will bless her, and moreover I will give you a son by her. Yes, I will bless her, and she will be a mother of nations. Kings of peoples will come from her.'

¹⁷  Then Abraham fell on his face, and laughed, and said in his heart, 'Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?'

¹⁸  Abraham said to God, 'Oh that Ishmael might live before you!'

¹⁹  God said, 'No, but Sarah, your wife, will bear you a son. You shall call his name Isaac.{Isaac means 'he laughs.'} I will establish my covenant with him for an everlasting covenant for his seed after him.

²⁰  As for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He will become the father of twelve princes, and I will make him a great nation.
