Bible: Genesis 17:15-21

17:15 Then God said to Abraham, “As for your wife, you must no longer call her Sarai; 1  Sarah 2  will be her name. 17:16 I will bless her and will give you a son through her. I will bless her and she will become a mother of nations. 3  Kings of countries 4  will come from her!

17:17 Then Abraham bowed down with his face to the ground and laughed 5  as he said to himself, 6  “Can 7  a son be born to a man who is a hundred years old? 8  Can Sarah 9  bear a child at the age of ninety? 10  17:18 Abraham said to God, “O that 11  Ishmael might live before you! 12 

17:19 God said, “No, Sarah your wife is going to bear you a son, and you will name him Isaac. 13  I will confirm my covenant with him as a perpetual 14  covenant for his descendants after him. 17:20 As for Ishmael, I have heard you. 15  I will indeed bless him, make him fruitful, and give him a multitude of descendants. 16  He will become the father of twelve princes; 17  I will make him into a great nation. 17:21 But I will establish my covenant with Isaac, whom Sarah will bear to you at this set time next year.”
