Alma 14:21; “And many such things did they say unto them, gnashing their teeth upon them, and spitting upon them, and saying: How shall we look when we are damned?”

John 7:17; “If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.”

Gal. 6:7; “Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.”

How does one go about gnashing their teeth upon someone?
