"Struck dumb"

1. Alma 30: 49-50
     49 Now Alma said unto him: This will I give unto thee for a sign, that thou shalt be struck dumb, according to my words; and I say, that in the name of God, ye shall be struck dumb, that ye shall no more have utterance.
     50 Now when Alma had said these words, Korihor was struck dumb, that he could not have utterance, according to the words of Alma.
2. Hel. 5: 25
     25 For they saw that the Lamanites durst not lay their hands upon them; neither durst they come near unto them, but stood as if they were struck dumb with amazement.
