'Innocent' in the Bible

Now in the morning he went out and stood and said to all the people, “You are innocent; behold, I conspired against my master and killed him, but who killed all these?

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

and also for the innocent blood which he shed, for he filled Jerusalem with innocent blood; and the Lord would not forgive.
