That's a good insight I didn't know about. I had that one wrong. I thought it was an expression of suffering from pain or something.

Holman Bible Dictionary:

Grating one's teeth together. In the Old Testament, gnashing of teeth was an expression of anger reserved for the wicked and for one's enemies (Job 16:9; Psalm 35:16; Psalm 37:12; Lamentations 2:16 ). In the New Testament, gnashing of teeth is associated with the place of future punishment (for example, Matthew 8:12; Matthew 13:42 ,Matthew 13:42,13:50 ). There the gnashing of teeth is perhaps an expression of the futility of the wicked before God's judgment or else a demonstration of their continuing refusal to repent and acknowledge the justness of God's judgment. (Compare Revelation 16:9 , Revelation 16:11 .) See Hell; Punishment, Everlasting.
