'Integrity' in the Bible

Did Abraham not tell me, ‘She is my sister?’ And she herself said, ‘He is my brother.’ In the integrity of my heart and innocence of my hands I have done this.”

Then God said to him in the dream, “Yes, I know you did this in the integrity of your heart, for it was I who kept you back and spared you from sinning against Me; therefore I did not give you an opportunity to touch her.
