How much worse will it be, then, when evil men kill an innocent man on his own bed in his own house! Shouldn't I avenge his blood which you are responsible for shedding by removing you from the earth?"

Then the woman of Tekoa said to the king, “My lord the king, may any blame be on me and my father’s house, and may the king and his throne be innocent.”

Meanwhile, 200 men left Jerusalem with Absalom. They had been invited to go along, but were innocent, not knowing anything about what was happening.

I have been innocent before him, and I've kept myself from incurring guilt.

You prove to be loyal to one who is faithful; you prove to be trustworthy to one who is innocent.
