Genesis 20:18-21:2

LEB(i) 18 For Yahweh had completely closed up all the wombs of the house of Abimelech because of the matter of Sarah, the wife of Abraham. 21 1 And Yahweh visited Sarah as he had said. And Yahweh did to Sarah as he had promised. 2 And she conceived, and Sarah bore to Abraham a son in his old age at the appointed time that God had told him.
