Helaman 5:33

and also again the third time the voice came, and did speak unto them marvellous words, which cannot be uttered by man; and the walls did tremble again, and the earth shook as if it were about to divide asunder.

The voice came a third time. It spoke amazing words that people cannot say. The walls shook again. The earth shook as if it would split apart.

Then a third time the voice spoke—words so amazing they can’t be written down. The walls trembled again, and the earth shook as if it would split apart.
