Genesis 21:9-16

One day Sarah saw the son that Hagar the Egyptian had borne to Abraham, poking fun at her son Isaac. She told Abraham, “Get rid of this slave woman and her son. No child of this slave is going to share inheritance with my son Isaac!” The matter gave great pain to Abraham—after all, Ishmael was his son. But God spoke to Abraham, “Don’t feel badly about the boy and your maid. Do whatever Sarah tells you. Your descendants will come through Isaac. Regarding your maid’s son, be assured that I’ll also develop a great nation from him—he’s your son, too.” Abraham got up early the next morning, got some food together and a canteen of water for Hagar, put them on her back and sent her away with the child. She wandered off into the desert of Beersheba. When the water was gone, she left the child under a shrub and went off, fifty yards or so. She said, “I can’t watch my son die.” As she sat, she broke into sobs.
