'Innocent' in the Bible

The next morning he went out and stood and said to all the people, “You are just and innocent; behold, I conspired against [Joram] my master and killed him, but who killed all these?

Moreover, Manasseh shed a very great quantity of innocent blood, until he had filled Jerusalem from one end to another; besides his sin with which he made Judah sin, by doing evil in the sight of the Lord.

and also for the innocent blood that he shed, for he filled Jerusalem with innocent blood; and the Lord would not pardon it.
