'Integrity' in the Bible

Did 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.

And God 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.
