Sarah said to Abraham, "Get rid of that slave woman. Get rid of her son. The slave woman's son will never have a share of the family's property with my son Isaac."
But God said to him, "Do not be so upset about the boy and your servant Hagar. Listen to what Sarah tells you, because your family line will continue through Isaac.
Early the next morning Abraham got some food and a bottle of water. The bottle was made out of animal skin. He gave the food and water to Hagar. He placed them on her shoulders. Then he sent her away with the boy. She went on her way and wandered in the desert of Beersheba.
Then she went off and sat down nearby. She was about as far away as a person can shoot an arrow. She thought, "I can't stand to watch the boy die." As she sat nearby, she began to sob.
God heard the boy crying. Then the angel of God called out to Hagar from heaven. He said to her, "What is the matter, Hagar? Do not be afraid. God has heard the boy crying as he lies there.
Now make a promise to me here while God is watching. Take an oath that you will treat me fairly. Promise that you will treat my children and their children the same way. "I've been kind to you. Now you be kind to me. And be kind to the country where you are living as an outsider."
