'Innocent' in the Bible

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

So when Pilate saw that nothing was being gained, but rather that a disturbance was starting, he took water, and washed his hands before the multitude, saying, "I am innocent of the blood of this righteous person. You see to it."

For those who are such don't serve our Lord, Jesus Christ, but their own belly; and by their smooth and flattering speech, they deceive the hearts of the innocent.

For your obedience has become known to all. I rejoice therefore over you. But I desire to have you wise in that which is good, but innocent in that which is evil.
