In his editing for the 1837 edition, Joseph Smith eliminated the modal verb shall near the beginning of Alma 37:2, perhaps because the preceding verse is very similar but does not have any modal:
Thus the change in verse 2 makes the beginning of the chapter read more consistently. Nonetheless, shall is clearly possible and is found in this context elsewhere in the text:
The critical text will therefore restore the occurrence of shall here in Alma 37:2.
Summary: Restore in Alma 37:2 the original shall in “I also command you that ye shall keep a record of this people”, despite the fact that the preceding verse lacks the shall (“I command you that ye take the records”); either usage occurs elsewhere in the text.
