Genesis 17:17-19

Expanded Bible

¹⁷ Abraham ·bowed facedown on the ground [^Lfell on his face] and laughed. He ·said to himself [thought; ^Lsaid in his heart], “Can a man have a child when he is a hundred years old? Can Sarah give birth to a child when she is ninety?” ¹⁸ Then Abraham said to God, “Please let Ishmael ·be the son you promised [^Llive before you].”

¹⁹ God said, “·No, [or Yes, but] Sarah your wife will have a son, and you will name him Isaac [^Crelated to the verb meaning “to laugh”]. I will make my ·agreement [covenant; treaty; 6:18] with him to be an ·agreement that continues forever [eternal covenant/treaty] with all his ·descendants [^Lseed].
