'Innocent' in the Bible

Now you also know what Joab the son of Zeruiah [my sister] did to me, and what he did to the two commanders of the armies of Israel, to Abner the son of Ner and to Amasa the son of Jether, [both of] whom he murdered; avenging the blood of war in [a time of] peace. And he put the [innocent] blood of war [of Abner and Amasa] on his belt that was around his waist, and on his sandals on his feet.

But now don't treat him as if he were innocent. You are a wise man and you know how to handle him; make sure he has a bloody death."

And the king said unto him, Do as he hath said, and fall upon him, and bury him; that thou mayest take away the innocent blood, which Joab shed, from me, and from the house of my father.

May the Lord punish him for the blood he shed; behind my father David's back he struck down and murdered with the sword two men who were more innocent and morally upright than he -- Abner son of Ner, commander of Israel's army, and Amasa son of Jether, commander of Judah's army.

Listen from heaven and make a just decision about your servants' claims. Condemn the guilty party, declare the other innocent, and give both of them what they deserve.
