Sarah saw Hagar's son laughing, the one Hagar the Egyptian had borne to Abraham.
So she said to Abraham, "Send this servant away with her son! This servant's son won't share the inheritance with my son Isaac."
This upset Abraham terribly because the boy was his son.
God said to Abraham, "Don't be upset about the boy and your servant. Do everything Sarah tells you to do because your descendants will be traced through Isaac.
But I will make of your servant's son a great nation too, because he is also your descendant."
Abraham got up early in the morning, took some bread and a flask of water, and gave it to Hagar. He put the boy in her shoulder sling and sent her away. She left and wandered through the desert near Beer-sheba.
Finally the water in the flask ran out, and she put the boy down under one of the desert shrubs.
She walked away from him about as far as a bow shot and sat down, telling herself, I can't bear to see the boy die. She sat at a distance, cried out in grief, and wept.
God heard the boy's cries, and God's messenger called to Hagar from heaven and said to her, "Hagar! What's wrong? Don't be afraid. God has heard the boy's cries over there.
Get up, pick up the boy, and take him by the hand because I will make of him a great nation."
Then God opened her eyes, and she saw a well. She went over, filled the water flask, and gave the boy a drink.
God remained with the boy; he grew up, lived in the desert, and became an expert archer.
