Here the 1858 Wright edition replaced the verb await with its variant wait. This shorter form has been continued in all the RLDS editions. The verb wait is the verb normally used in the text for any general kind of waiting. On the other hand, the verb is typically await when there is some sense of anxiousness in the waiting, although all the examples except for two (one in 3 Nephi 3:3 and the other here in Mormon 6:7) refer to some sort of deserved punishment that metaphorically “awaits” the sinner:
The original use of await in Mormon 6:7 is appropriate and will be retained in the critical text.
Summary: Accept in Mormon 6:7 the use of await, the reading of the earliest text; the verb await is appropriate here since the context implies anxiousness.
