Although 𝓞 is not extant here, it most probably read bordered, which Oliver miswrote as bored when he copied the text from 𝓞 into 𝓟. Of course, bored is impossible here, and bordered (the 1830 typesetter’s emendation) is undoubtedly correct. The verb border occurs only five times elsewhere in the text, but three of these are found in the immediately preceding verses 27–29 (see the list below in the following discussion). The critical text will maintain the reading bordered here in verse 30.
Summary: Maintain the occurrence of the verb bordered in Alma 22:30, the 1830 typesetter’s obviously correct emendation.
