Isaac is born.
Genesis 21:1 And the LORD visited Sarah as he had said, and the LORD did to Sarah as he had spoken. Genesis 21:2 For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him. Genesis 21:3 And Abraham called the name of his son that was born to him, whom Sarah bore to him, Isaac.
He is circumcised.
Genesis 21:4 And Abraham circumcised his son Isaac, being eight days old, as God had commanded him. Genesis 21:5 And Abraham was a hundred years old, when his son Isaac was born to him.
Genesis 21:6 And Sarah said, God hath made me to laugh, [so that] all that hear will laugh with me. Genesis 21:7 And she said, Who would have said to Abraham, that Sarah shall nurse children? for I have borne him a son in his old age. Genesis 21:8 And the child grew, and was weaned: and Abraham made a great feast the day that Isaac was weaned.
Hagar and Ishmael are cast forth.
Genesis 21:9 And Sarah saw the son of Hagar the Egyptian, which she had borne to Abraham, mocking. Genesis 21:10 Wherefore, she said to Abraham, Cast out this bond-woman, and her son: for the son of this bond-woman shall not be heir with my son, [even] with Isaac. Genesis 21:11 And the thing was very grievous in Abraham's sight, because of his son.
Genesis 21:12 And God said to Abraham, Let it not be grievous in thy sight, because of the lad, and because of thy bond-woman; in all that Sarah hath said to thee, hearken to her voice: for in Isaac shall thy seed be called. Genesis 21:13 And also of the son of the bond-woman will I make a nation, because he [is] thy seed. Genesis 21:14 And Abraham rose early in the morning, and took bread, and a bottle of water, and gave [it] to Hagar (putting [it] on her shoulder) and the child, and sent her away; and she departed, and wandered in the wilderness of Beer-sheba.
Hagar in distress.
Genesis 21:15 And the water was spent in the bottle, and she cast the child under one of the shrubs. Genesis 21:16 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 raised her voice, and wept.
The angel comforteth her.
Genesis 21:17 And God heard the voice of the lad: and the angel of God called to Hagar out of heaven, and said to her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he [is]. Genesis 21:18 Arise, lift up the lad, and hold him in thy hand: for I will make him a great nation. Genesis 21:19 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. Genesis 21:20 And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer. Genesis 21:21 And he dwelt in the wilderness of Paran: and his mother took for him a wife out of the land of Egypt.
Abimelech's covenant with Abraham at Beer-sheba.
Genesis 21:22 And it came to pass at that time, that Abimelech, and Phichol the chief captain of his host, spoke to Abraham, saying, God [is] with thee in all that thou doest: Genesis 21:23 Now therefore swear to me here by God, that thou wilt not deal falsely with me, nor with my son, nor with my son's son: [but] according to the kindness that I have done to thee, thou shalt do to me, and to the land in which thou hast sojourned. Genesis 21:24 And Abraham said, I will swear. Genesis 21:25 And Abraham reproved Abimelech, because of a well of water, which Abimelech's servants had violently taken away. Genesis 21:26 And Abimelech said, I know not who hath done this thing: neither didst thou tell me, neither yet have I heard [of it], but to-day. Genesis 21:27 And Abraham took sheep and oxen, and gave them to Abimelech: and both of them made a covenant. Genesis 21:28 And Abraham set seven ewe-lambs of the flock by themselves. Genesis 21:29 And Abimelech said to Abraham, What [mean] these seven ewe-lambs, which thou hast set by themselves? Genesis 21:30 And he said, For [these] seven ewe-lambs shalt thou take from my hand, that they may be a witness to me, that I have digged this well. Genesis 21:31 Wherefore he called that place Beer-sheba: because there they swore both of them. Genesis 21:32 Thus they made a covenant at Beer-sheba: Then Abimelech arose, and Phichol the chief captain of his host, and they returned into the land of the Philistines.
Genesis 21:33 And [Abraham] planted a grove in Beer-sheba, and called there on the name of the LORD, the everlasting God. Genesis 21:34 And Abraham sojourned in the land of the Philistines many days.
