Genesis 20:2-8

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

3But 1God came to Abimelech in a dream by night, and said to him, Behold, thou art [but] a dead man, because of the woman that thou hast taken; for she is a man's wife.

4But Abimelech had not come near her. And he said, Lord, wilt thou also kill a righteous nation?

5Did he not say to me, She is my sister? and she, even she said, He is my brother. In the integrity of my heart and in the innocency of my hands have I done this.

6And 2God said to him in a dream, I also knew that thou didst this in the integrity of thy heart, and I, too, have withheld thee from sinning against me: therefore have I not suffered thee to touch her.

7And now, restore the man's wife; for he is a prophet, and will pray for thee, that thou mayest live. And if thou do not restore [her], know that thou shalt certainly die, thou and all that is thine.

8And Abimelech rose early in the morning, and called all his servants, and spoke all these words in their ears; and the men were greatly afraid.
