Could not open mouth

1. Mosiah 27: 19
     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.
2. Alma 36: 10
     10 And it came to pass that I fell to the earth; and it was for the space of three days and three nights that I could not open my mouth, neither had I the use of my limbs.
