Genesis 17:15-17

New International Version - UK

¹⁵ God also said to Abraham, ‘As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. ¹⁶ I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.’

¹⁷ Abraham fell face down; he laughed and said to himself, ‘Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?’
