Here the original text apparently read “this their times of affliction”. The number disagreement between this and times led to changing times to time in the 1852 LDS edition. The LDS text has continued with the singular time.
There are a few instances in the original text of “this ”, as explained under Mosiah 7:23. Besides the example here in Alma 55:31, we also have “and is not this our afflictions great” (in Mosiah 7:23) and “ye shall go on in this your ways of sin” (in Helaman 9:21). The critical text will therefore restore the original plural noun times here in Alma 55:31.
Summary: Restore in Alma 55:31 the original plural times (“in this their times of affliction”), the reading of the earliest textual sources (including both manuscripts).
