'Accusation' in the Bible

Oh that I had one to hear me! Behold my signature: let the Almighty answer me! And let mine opponent write an accusation!

‘For he adds rebellion [in his unsubmissive, defiant attitude toward God] to his [unacknowledged] sin;He claps his hands among us [in open mockery and contempt of God],And he multiplies his words [of accusation] against God.’”
