'Innocent' in the Bible

The next morning when he went out and stood at the gate, he said to all the people, “You are innocent. It was I who conspired against my master and killed him. But who struck down all these?

Manasseh also shed so much innocent blood that he filled Jerusalem with it from one end to another. This was in addition to his sin that he caused Judah to commit. Consequently, they did what was evil in the Lord’s sight.

and also because of all the innocent blood he had shed. He had filled Jerusalem with innocent blood, and the Lord would not forgive.
