'Innocent' in the Bible

saying, I have sinned in that I betrayed innocent blood. But they said, What is that to us? see thou to it .

So when Pilate saw that he prevailed nothing, but rather that a tumult was arising, he took water, and washed his hands before the multitude, saying, I am innocent of the blood of this righteous man; see ye to it .

For they that are such serve not our Lord Christ, but their own belly; and by their smooth and fair speech they beguile the hearts of the innocent.
