Genesis 21:8-14

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 was very upset over Sarah’s demand, for Ishmael was his son too. God spoke to Abraham, “Don’t be distressed over the slave woman and her son. Listen to every word Sarah says to you, and do it, for it will be through Isaac your promise of descendants will be fulfilled. Rest assured, I will make the son of your slave woman into a nation too, because he is your son.” 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.
