Genesis 20:6

3 But 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.”

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

5 Didn’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.”

6 God 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.

7 Now 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.”

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

9 Then 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!”
