Genesis 21:5, 8-20a
5 when he was one hundred years old. Indeed, at this stage of his father's life, Isaac was born.
8 And the boy grew and was weaned. And Abraham made a great feast on the day of his weaning.
9 And when Sarah had seen the son of Hagar the Egyptian playing with her son Isaac, she said to Abraham:
10 "Cast out this woman servant and her son. For the son of a woman servant will not be heir with my son Isaac."
11 Abraham took this grievously, for the sake of his son.
12 And God said to him: "Let it not seem harsh to you concerning the boy and your woman servant. In all that Sarah has said to you, listen to her voice. For your offspring will be invoked in Isaac.
13 Yet I will also make the son of the woman servant into a great nation, for he is your offspring."
14 And so Abraham arose in the morning, and taking bread and a skin of water, he placed it upon her shoulder, and he handed over the boy, and he released her. And when she had departed, she wandered in the wilderness of Beersheba.
15 And when the water in the skin had been consumed, she set aside the boy, under one of the trees that were there.
16 And she moved away and sat in a distant area, as far as a bow can reach. For she said, "I shall not see the boy die." And so, sitting opposite her, he lifted up his voice and wept.
17 But God heard the voice of the boy. And an Angel of God called to Hagar from heaven, saying: "What are you doing, Hagar? Do not be afraid. For God has heeded the voice of the boy, from the place where he is.
18 Rise up. Take the boy and hold him by the hand. For I will make of him a great nation."
19 And God opened her eyes. And seeing a well of water, she went and filled the skin, and she gave the boy to drink.
20 And God was with him.
