'Prosecutor' in the Bible

"Just you wait!" declares the LORD. "The day will come when I stand up as a prosecutor, for I am determined to assemble the nations and to gather the kingdoms, in order to pour out my indignation upon them all of my fierce anger. All the earth will be consumed by the fire of my jealousy.

Agree with your adversary quickly, while you are with him in the way; lest perhaps the prosecutor deliver you to the judge, and the judge deliver you to the officer, and you be cast into prison.
