"I should be destroyed"

1. Alma 36: 11
     11 And the angel spake more things unto me, which were heard by my brethren, but I did not hear them; for when I heard the words—If thou wilt be destroyed of thyself, seek no more to destroy the church of God—I was struck with such great fear and amazement lest perhaps I should be destroyed, that I fell to the earth and I did hear no more.
2. JS-H 1: 42
     42 Again, he told me, that when I got those plates of which he had spoken—for the time that they should be obtained was not yet fulfilled—I should not show them to any person; neither the breastplate with the Urim and Thummim; only to those to whom I should be commanded to show them; if I did I should be destroyed. While he was conversing with me about the plates, the vision was opened to my mind that I could see the place where the plates were deposited, and that so clearly and distinctly that I knew the place again when I visited it.
