27:18 And now Alma and those that were with him fell again to the earth, for great was their astonishment; for with their own eyes they had beheld an angel of the Lord; and his voice was as thunder, which shook the earth; and they knew that there was nothing save the power of God that could shake the earth and cause it to tremble as though it would part asunder.

 27:19 And now the astonishment of Alma was so great that he became dumb, that he could not open his mouth; yea, and he became weak, even that he could not move his hands; therefore he was taken by those that were with him, and carried helpless, even until he was laid before his father.
