As noted under Alma 12:12–14, there are numerous places in the text where work(s) and word(s) have been mixed up, including here in Alma 53:10. In this instance, the 1953 RLDS edition accidentally replaced word with work. Elsewhere in the text, we have a number of cases where word and power are conjoined, but none of work and power:
Summary: Maintain the original reading in Alma 53:10, which conjoins power and word; the 1953 RLDS reading of work is a typo; power and word are typically conjoined in the text, but never power and work.
