Genesis 20:6

2Abraham said about Sarah his wife, “She is my sister.” Abimelech king of Gerar sent, and took Sarah.

3But God came to Abimelech in a dream of the night, and said to him, “Behold, you are a dead man, because of the woman whom you have taken; for she is a man’s wife.”

4Now Abimelech had not come near her. He said, “Lord, will you kill even a righteous nation?

5Didn’t he tell me, ‘She is my sister’? She, even she herself, said, ‘He is my brother.’ I have done this in the integrity of my heart and the innocence of my hands.”

6God said to him in the dream, “Yes, I know that in the integrity of your heart you have done this, and I also withheld you from sinning against me. Therefore I didn’t allow you to touch her.

7Now therefore, restore the man’s wife. For he is a prophet, and he will pray for you, and you will live. If you don’t restore her, know for sure that you will die, you, and all who are yours.”

8Abimelech rose early in the morning, and called all his servants, and told all these things in their ear. The men were very scared.

9Then Abimelech called Abraham, and said to him, “What have you done to us? How have I sinned against you, that you have brought on me and on my kingdom a great sin? You have done deeds to me that ought not to be done!”

10Abimelech said to Abraham, “What did you see, that you have done this thing?”
