Genesis 21:9-16

9And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, scoffing.

10Therefore she said to Abraham, “Cast out this bondwoman and her son; for the son of this bondwoman shall not be heir with my son, namely with Isaac.”

11And the matter was very displeasing in Abraham’s sight because of his son.

12But God said to Abraham, “Do not let it be displeasing in your sight because of the lad or because of your bondwoman. Whatever Sarah has said to you, listen to her voice; for in Isaac your seed shall be called.

13Yet I will also make a nation of the son of the bondwoman, because he is your seed.”

14So Abraham rose early in the morning, and took bread and a skin of water; and putting it on her shoulder, he gave it and the boy to Hagar, and sent her away. Then she departed and wandered in the Wilderness of Beersheba.

15And the water in the skin was used up, and she placed the boy under one of the shrubs.

16Then she went and sat down across from him at a distance of about a bowshot; for she said to herself, “Let me not see the death of the boy.” So she sat opposite him, and lifted her voice and wept.
