As discussed under 1 Nephi 2:5 and 1 Nephi 3:28, the scribes sometimes mixed up brethren and brothers. In this example from 1 Nephi 13:10, the unknown scribe 2 of 𝓞 initially wrote the plural form Brethers (a fairly frequent misspelling in the manuscripts for brothers), but here he immediately caught his error and corrected it to Brethren. His corrected form was copied into 𝓟 and the 1830 edition. The critical text will maintain the use of brethren here in 1 Nephi 13:10.
