Genesis 21:9-14

9Now [as time went on] Sarah saw [Ishmael] the son of Hagar the Egyptian, whom she had borne to Abraham, mocking [Isaac].

10Therefore 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.”

11The situation distressed Abraham greatly because of his son [Ishmael].

12God said to Abraham, “Do not let it distress you because of Ishmael and your maid; whatever Sarah tells you, listen to her and do what she asks, for your descendants will be named through Isaac.

13And I will also make a nation of [Ishmael] the son of the maid, because he is your descendant.”

14So Abraham got up 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 left [but lost her way] and wandered [aimlessly] in the Wilderness of Beersheba.
