'Gnashed' in the Bible

His wrath has torn, and he has been hostile toward me; he gnashed at me with his teeth. My foe sharpens his eyes against me.

Among [the] ungodly of the mockers at feasts, [they] gnashed at me with their teeth.

Now [when they] heard these [things], they were infuriated in their hearts and gnashed [their] teeth at him.
