'Innocence' 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.”

I shall wash my hands in innocence,And I will go about Your altar, O Lord,

Surely in vain I have kept my heart pureAnd washed my hands in innocence;

He has rejected your calf, O Samaria, saying,“My anger burns against them!”How long will they be incapable of innocence?
