Psalm 35:16

“His anger has torn me and hunted me down; He has gnashed at me with His teeth; My adversary sharpens his eyes to look at me.

The wicked schemes against the righteous And gnashes at him with his teeth.

The wicked will see it and be vexed, He will gnash his teeth and melt away; The desire of the wicked will perish.

All your enemies Have opened their mouths wide against you; They hiss and gnash their teeth. They say, “We have swallowed her up! Surely this is the day for which we have hoped; We have found it, we have seen it.”
