'Accuser' in the Bible

Reach agreement quickly with your accuser while on the way to court, or he may hand you over to the judge, and the judge hand you over to the warden, and you will be thrown into prison.

As you are going with your accuser before the magistrate, make an effort to settle with him on the way, so that he will not drag you before the judge, and the judge hand you over to the officer, and the officer throw you into prison.

Do not think that I will accuse you to the Father. Your accuser is Moses, on whom you have set your hope.

Jesus answered them, “Did I not choose you, the twelve [disciples]? And yet one of you is a devil (ally of Satan).”

Curb every passion, and be on the alert. Your great accuser, the Devil, is going about like a roaring lion to see whom he can devour.

And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
