Genesis 20:2-8

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

3But God came to Abimelech in a dream at night and said to him, “Behold, you are as good as dead, because of the woman whom you have taken—since she is a married woman.”

4Now Abimelech had not come near her. So he said, “My Lord, will You slay a nation, even though innocent?

5Didn’t he say to me, ‘She’s my sister’? And she herself even said, ‘He’s my brother.’ I did this with integrity of my heart and guiltlessness of my hands.”

6Then God said to him in a dream, “Yes, I myself knew that you did this with integrity of your heart, so I, yes I Myself prevented you from sinning against Me. That is why I did not allow you to touch her.

7So now, return the man’s wife, for he is a prophet. And let him pray for you and you will live. But if you do not return her, know that you will surely die—you and all who are yours.”

8Abimelech rose early in the morning, called all his servants and spoke all these words in their ears—and the men were very frightened.
