Genesis 17:17-19

Amplified Bible, Classic Edition

¹⁷ Then Abraham fell on his face and laughed and said in his heart, Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a son?

¹⁸ And [he] said to God, Oh, that Ishmael might live before You!

¹⁹ But God said, Sarah your wife shall bear you a son indeed, and you shall call his name Isaac [laughter]; and I will establish My covenant or solemn pledge with him for an everlasting covenant and with his posterity after him.
