Here in 𝓞, Oliver Cowdery initially wrote “these provisions”. Virtually immediately, he corrected these to those by overwriting the e with an o (there is no difference in the level of ink flow). Here the critical text will maintain the corrected reading in 𝓞. Elsewhere in this chapter, Oliver Cowdery twice mixed up these and those when he copied the text from 𝓞 into 𝓟. For these examples, see under verses 16 and 20. For a general list of cases where Oliver switched these demonstratives, see under Alma 3:25. The critical text will in each case of these /those follow the earliest textual sources.
Summary: Maintain in Alma 57:11 the corrected reading in 𝓞, “those provisions”.
