Alma Departs for the City of Melek and Is Never Heard from Again
18 And when Alma had done this he departed out of the land of Zarahemla, as if to go into the land of Melek. And it came to pass that he was never heard of more; as to his death or burial we know not of.
19 Behold, this we know, that he was a righteous man; and the saying went abroad in the church that he was taken up by the Spirit, or buried by the hand of the Lord, even as Moses. But behold, the scriptures saith the Lord took Moses unto himself; and we suppose that he has also received Alma in the spirit, unto himself; therefore, for this cause we know nothing concerning his death and burial.
Elder Bruce R. McConkie wrote:
“Moses, Elijah, and Alma the younger, were translated. The Old Testament account that Moses died and was buried by the hand of the Lord in an unknown grave is an error (see Deut. 34:5–7). It is true that he may have been ‘buried by the hand of the Lord,’ if that expression is a figure of speech which means that he was translated. But the Book of Mormon account, in recording that Alma ‘was taken up by the Spirit,’ says, ‘the scriptures saith the Lord took Moses unto himself; and we suppose that he has also received Alma in the spirit, unto himself’ (Alma 45:18–19).”
