Genesis 21:9-13

CAB(i) 9 And Sarah, having seen the son of Hagar the Egyptian, who was born to Abraham, sporting with Isaac her son, 10 that she said to Abraham, Cast out this bondwoman and her son, for the son of this bondwoman shall not inherit with my son Isaac. 11 But the word appeared very distressing before Abraham concerning his son. 12 But God said to Abraham, Let it not be distressing before you concerning the child, and concerning the bondwoman; whatever Sarah shall say to you, listen to her voice, for in Isaac shall your seed be called. 13 And moreover, I will make the son of this bondwoman a great nation, because he is your seed.
