Here the text could theoretically read as either “and thus they did” or “and this they did”. Under Alma 24:17–18, I provided evidence that in cases of this versus thus the critical text will normally follow the earliest textual reading unless there is specific evidence to make us think there might be a textual error. Here in Alma 52:24–25, the earliest thus (the reading in 𝓞) will be maintained. It should be noted that under Alma 11:21 I had indicated I would discuss this item in part 4, but I neglected to do so; thus I have added this brief discussion as an addendum.
Summary: Maintain thus in Alma 52:25, the reading of all the textual sources (including 𝓞).
