Numbers 33 records that after departing from Mount Hor, Israel camped at Zalmonah. From Zalmonah the Israelites traveled to Punon and then onward toward Oboth.
The itinerary places Zalmonah after the death of Aaron at Mount Hor and during Israel's movement toward the Transjordanian approach to Canaan.
The passage provides no additional narrative concerning events specifically occurring at Zalmonah.
