Genesis 21:8-10, 14-16

Isaac grew and was weaned; and on the day Sarah weaned him, Abraham prepared a great feast. But Sarah noticed the son of Hagar, the Egyptian, was mocking her son Isaac. So she said to Abraham, “Get rid of this slave woman and her son. Banish them, for the son of that slave woman must not become a coheir with my son Isaac!”

Abraham rose up early the next morning, bundled up some food and a skin of water, and strapped them to Hagar’s shoulders. Then he gave her his son and sent them away. So, Hagar and her son Ishmael departed and wandered off into the wilderness of Beersheba. When the water was gone, she grew desperate, so she left her son under a bush. Then she walked about the distance of a bowshot and sat down, for she thought, “I can’t bear to watch my son die.” As she sat nearby, she broke into tears and sobbed uncontrollably.
