Idolatry or idleness

A few passages in the Book of Mormon appear to contain errors immediately followed by corrections. This is probably the most obvious instance:

. . . and thus we see that they buried their weapons of peace, or they buried the weapons of war, for peace (Alma 24:19).

Since "weapons of peace" doesn't make any sense, the "or" seems to be a correction, meaning "or rather." Since one can't easily erase an error once it has been engraved on a gold plate, it makes sense that errors would be corrected in this way. Alternatively, "weapons of peace" could have been Joseph Smith's slip of the tongue rather than a mistake on the plates, but that seems less likely, since his scribe could have just crossed out the incorrect phrase and written the correct one. The mistake itself could have been made in any language, though.

The following example from Alma, though, seems like it must have been a slip of the tongue on Joseph's part, since it is only in English that idolatry and idleness sound similar.

For those who did not belong to their church did indulge themselves in sorceries, and in idolatry or idleness, and in babblings, and in envyings and strife . . . (Alma 1:32).

This seems to be an error and correction because "idolatry or idleness" is such an odd expression otherwise. The two concepts seem to be unrelated, but they do sound similar in English. However, another possibility is that the text really is equating idolatry with idleness to make some point -- something along the lines of "fasting and prayer, or otherwise rejoicing and prayer" (D&C 59:14). Three other passages in the Book of Mormon, which pair idolatry with idleness but without using similar-sounding words, suggest that this is in fact the case:

Now they were a lazy and an idolatrous people; therefore they were desirous to bring us into bondage, that they might glut themselves with the labors of our hands; yea, that they might feast themselves upon the flocks of our fields (Mosiah 9:12).

Yea, and thus they were supported in their laziness, and in their idolatry, and in their whoredoms, by the taxes which king Noah had put upon his people; thus did the people labor exceedingly to support iniquity (Mosiah 11:6).

Thus they were a very indolent people, many of whom did worship idols, and the curse of God had fallen upon them because of the traditions of their fathers; notwithstanding the promises of the Lord were extended unto them on the conditions of repentance (Alma 17:15).

This juxtaposition does not occur in the Bible. The closest thing I can think of conceptually is the occasional references to idols as "vanities," for example:

They have moved me to jealousy with that which is not God; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish nation (Deut. 32:31).

The Hebrew words translated "vanities," and pretty clearly referring to the worship of "that which is not God," means "emptiness, futility, uselessness" and is thus conceptually akin to idleness. So perhaps that is the idea behind the "laziness and idolatry" passages in the Book of Mormon: useless people who worship useless things.
