Genesis 16
16 Now Sarai, Abram’s wife, had borne him no children. And she had an Egyptian maidservant whose name was Hagar. 2 So Sarai said to Abram, “See now, the Lord has restrained me from bearing children. Please, go in to my maid; perhaps I shall obtain children by her.” And Abram heeded the voice of Sarai. 3 Then Sarai, Abram’s wife, took Hagar her maid, the Egyptian, and gave her to her husband Abram to be his wife, after Abram had dwelt ten years in the land of Canaan. 4 So he went in to Hagar, and she conceived. And when she saw that she had conceived, her mistress became despised in her eyes.
5 Then Sarai said to Abram, “My wrong be upon you! I gave my maid into your embrace; and when she saw that she had conceived, I became despised in her eyes. The Lord judge between you and me.”
6 So Abram said to Sarai, “Indeed your maid is in your hand; do to her as you please.” And when Sarai dealt harshly with her, she fled from her presence.
7 Now the Angel of the Lord found her by a spring of water in the wilderness, by the spring on the way to Shur. 8 And He said, “Hagar, Sarai’s maid, where have you come from, and where are you going?”
She said, “I am fleeing from the presence of my mistress Sarai.”
9 The Angel of the Lord said to her, “Return to your mistress, and submit yourself under her hand.” 10 Then the Angel of the Lord said to her, “I will multiply your descendants exceedingly, so that they shall not be counted for multitude.” 11 And the Angel of the Lord said to her:
“Behold, you are with child,
And you shall bear a son.
You shall call his name Ishmael,
Because the Lord has heard your affliction.
12 He shall be a wild man;
His hand shall be against every man,
And every man’s hand against him.
And he shall dwell in the presence of all his brethren.”
13 Then she called the name of the Lord who spoke to her, You-Are-the-God-Who-Sees; for she said, “Have I also here seen Him who sees me?” 14 Therefore the well was called Beer Lahai Roi;[a] observe, it is between Kadesh and Bered.
15 So Hagar bore Abram a son; and Abram named his son, whom Hagar bore, Ishmael. 16 Abram was eighty-six years old when Hagar bore Ishmael to Abram.

Genesis 21
21 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken.
2 For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
3 And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
4 And Abraham circumcised his son Isaac being eight days old, as God had commanded him.
5 And Abraham was an hundred years old, when his son Isaac was born unto him.
6 And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7 And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.
8 And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.
10 Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
11 And the thing was very grievous in Abraham's sight because of his son.
12 And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called.
13 And also of the son of the bondwoman will I make a nation, because he is thy seed.
14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.
15 And the water was spent in the bottle, and she cast the child under one of the shrubs.
16 And she went, and sat her down over against him a good way off, as it were a bow shot: for she said, Let me not see the death of the child. And she sat over against him, and lift up her voice, and wept.
17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.
18 Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.
19 And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink.
20 And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer.
21 And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt.
