Cambridge Bible for Schools and Colleges:

utterly destroyed] banned or devoted. The ‘ban’ (ḥérem) was an archaic institution, often alluded to in the OT. A city or nation that was hostile to Jehovah was ‘banned,’ or ‘devoted’ (etymologically, as Arabic shews, separated or set apart1[189]), i.e. given over to Him as a form of offering, human beings being destroyed, with or without the cattle and spoil as well, according to the gravity of the occasion.

Gill explained:

he shall be utterly destroyed; be accursed, anathematized, devoted to destruction.

Deuteronomy 2:

34 And we captured all his cities at that time and devoted to destruction every city, men, women, and children. We left no survivors.

H4191-put-to-death was a generic word for killing. H2763-devoted-to-destruction was a more solemn form of holy killing. It carried a more religious connotation.
