Genesis 20:4-6 (King James Version)

 ⁴But Abimelech had not come near her: and he said, LORD, wilt thou slay also a righteous nation?

 ⁵Said he not unto me, She is my sister? and she, even she herself said, He is my brother: in the integrity of my heart and innocency of my hands have I done this.

 ⁶And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.
