'Innocent' in the Bible

When David later heard about this, he said, "I and my kingdom are forever innocent before the Lord of the shed blood of Abner son of Ner!

Surely when wicked men have killed an innocent man as he slept in his own house, should I not now require his blood from your hands and remove you from the earth?"

The Tekoan woman said to the king, "My lord the king, let any blame fall on me and on the house of my father. But let the king and his throne be innocent!"

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