9 Now Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking. 10 Therefore she said to Abraham, “Drive out this maid and her son, for the son of this maid shall not be an heir with my son Isaac.” 11 The matter distressed Abraham greatly because of his son. 12 But God said to Abraham, “Do not be distressed because of the lad and your maid; whatever Sarah tells you, listen to her, for through Isaac your descendants shall be named. 13 “And of the son of the maid I will make a nation also, because he is your descendant.” 14 So Abraham rose early in the morning and took bread and a skin of water and gave them to Hagar, putting them on her shoulder, and gave her the boy, and sent her away. And she departed and wandered about in the wilderness of Beersheba.
15 When the water in the skin was used up, she left the boy under one of the bushes. 16 Then she went and sat down opposite him, about a bowshot away, for she said, “Do not let me see the boy die.” And she sat opposite him, and lifted up her voice and wept. 17 God heard the lad crying; and the angel of God called to Hagar from heaven and said to her, “What is the matter with you, Hagar? Do not fear, for God has heard the voice of the lad where he is. 18 “Arise, lift up the lad, and hold him by the hand, for I will make a great nation of him.” 19 Then God opened her eyes and she saw a well of water; and she went and filled the skin with water and gave the lad a drink.
20 God was with the lad, and he grew; and he lived in the wilderness and became an archer. 21 He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt.
Things were not looking good for Hagar this time. The first time, she had been allowed to come back and live with Abraham and Sarah. That was not an option this time, and she had no one to take care of her now. But God would take care of her, and her son. When God heard them weeping, He answered, and provided a well in the wilderness. Even when there was nothing to sustain Hagar, God took care of her.
