New American Standard Bible (NASB)
Genesis 20
11 Abraham said, "Because I thought, surely there is no fear of God in this place, and they will kill me because of my wife.
12 Besides, she actually is my sister, the daughter of my father, but not the daughter of my mother, and she became my wife;
13 and it came about, when God caused me to wander from my father’s house, that I said to her, ’This is the kindness which you will show to me: everywhere we go, say of me, "He is my brother."’"
14 Abimelech then took sheep and oxen and male and female servants, and gave them to Abraham, and restored his wife Sarah to him.
15 Abimelech said, "Behold, my land is before you; settle wherever you please."
16 To Sarah he said, "Behold, I have given your brother a thousand pieces of silver; behold, it is your vindication before all who are with you, and before all men you are cleared."
17 Abraham prayed to God, and God healed Abimelech and his wife and his maids, so that they bore children.
18 For the Lord had closed fast all the wombs of the household of Abimelech because of Sarah, Abraham’s wife.
Genesis 21
1 Then the Lord took note of Sarah as He had said, and the Lord did for Sarah as He had promised.
2 So Sarah conceived and bore a son to Abraham in his old age, at the appointed time of which God had spoken to him.
3 Abraham called the name of his son who was born to him, whom Sarah bore to him, Isaac.
