Genesis 21:12-21

But God told Abraham, “Do not be upset over the boy and your servant. Do whatever Sarah tells you, for Isaac is the son through whom your descendants will be counted. But I will also make a nation of the descendants of Hagar’s son because he is your son, too.” So Abraham got up early the next morning, prepared food and a container of water, and strapped them on Hagar’s shoulders. Then he sent her away with their son, and she wandered aimlessly in the wilderness of Beersheba. When the water was gone, she put the boy in the shade of a bush. Then she went and sat down by herself about a hundred yards away. “I don’t want to watch the boy die,” she said, as she burst into tears. But God heard the boy crying, and the angel of God called to Hagar from heaven, “Hagar, what’s wrong? Do not be afraid! God has heard the boy crying as he lies there. Go to him and comfort him, for I will make a great nation from his descendants.” Then God opened Hagar’s eyes, and she saw a well full of water. She quickly filled her water container and gave the boy a drink. And God was with the boy as he grew up in the wilderness. He became a skillful archer, and he settled in the wilderness of Paran. His mother arranged for him to marry a woman from the land of Egypt.
