Genesis 20:2-8

2Abraham said of Sarah his wife, “1She is my sister.” So 2Abimelech king of Gerar sent and took Sarah. 33But God came to Abimelech in a dream of the night, and said to him, “Behold, 4you are a dead man because of the woman whom you have taken, for she is 5married.” 4Now Abimelech had not come near her; and he said, “Lord, 6will You slay a nation, even though 7blameless? 5Did he not himself say to me, ‘She is my sister’? And she 8herself said, ‘He is my brother.’ In 9the integrity of my heart and the innocence of my 10hands I have done this.” 6Then God said to him in the dream, “Yes, I know that in the integrity of your heart you have done this, and I also 1112kept you from sinning against Me; therefore I did not let you touch her. 7Now therefore, restore the man’s wife, for 13he is a prophet, and he will pray for you and you will live. But if you do not restore her, know that you shall surely die, you and all who are yours.”

8So Abimelech arose early in the morning and called all his servants and told all these things in their hearing; and the men were greatly frightened.
