Genesis 20:2-8

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

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

4But Abimelech had not come near her; and he said, “Lord, will You slay a righteous nation also?

5Did he not say to me, ‘She is my sister’? And she, even she herself said, ‘He is my brother.’ In the integrity of my heart and innocence of my hands I have done this.”

6And God said to him in a dream, “Yes, I know that you did this in the integrity of your heart. For I also withheld you from sinning against Me; therefore I did not let you touch her.

7Now therefore, restore the man’s wife; for he is a prophet, and he will pray for you and you shall live. But if you do not restore her, know that you shall surely die, you and all who are yours.”

8So Abimelech rose early in the morning, called all his servants, and told all these things in their hearing; and the men were very much afraid.
