Alma’s blessing and counsel to Helaman spoke to Helaman as a person, but also as a record keeper with a responsibility to the people. Shiblon does not share those responsibilities, but he is still given a personal blessing. It is interesting that although Alma has already praised him and indicated that he knows that he will have joy in Shiblon (see verse 2), these admonitions are for what he should not do, rather than a list of things that he should do, as was given to Helaman.
Perhaps Alma saw this as a complementary blessing to Helaman. Where that blessing gives a “do this” list, Shiblon’s blessing gives a “don’t do this” list. Both are applicable to all modern readers. There are things we should do, and things we should not.
As noted in the discussion of the header for this chapter, it is also possible that Mormon is using these blessings as types for his readers, and that he had edited this blessing to have Shiblon as the representative of so many of us who are basically faithful, but who might be tempted by the things of the world.
This is the end of a chapter in the 1830 edition.
