Genesis 20:1-6
Abraham and Abimelech
20:1 Abraham journeyed from there to the Negev region and settled between Kadesh and Shur. While he lived as a temporary resident in Gerar,
20:2 Abraham said about his wife Sarah, “She is my sister.” So Abimelech, king of Gerar, sent for Sarah and took her.
20:3 But God appeared to Abimelech in a dream at night and said to him, “You are as good as dead because of the woman you have taken, for she is someone else’s wife.”
20:4 Now Abimelech had not gone near her. He said, “Lord, would you really slaughter an innocent nation?
20:5 Did Abraham not say to me, ‘She is my sister’? And she herself said, ‘He is my brother.’ I have done this with a clear conscience and with innocent hands!”
20:6 Then in the dream God replied to him, “Yes, I know that you have done this with a clear conscience. That is why I have kept you from sinning against me and why I did not allow you to touch her.
