'Integrity' in the Bible

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

Then God said to him in the dream, “Yes, I know that in the integrity of your heart you have done this, and I also kept you from sinning against Me; therefore I did not let you touch her.
