Barnes' Notes on the Whole Bible

Zalmonah and Punon are stations on the Pilgrim’s road; and the general route is fairly ascertained by a comparison of these verses with Numbers 21:4, etc.

The expulsion of the Canaanites and the destruction of their monuments of idolatry had been already enjoined (see the marginal references); and Numbers 33:54 is substantially a repetition from Exo. 26:53-55. But the solemn warning of Numbers 33:55-56 is new. A call for it had been furnished by their past transgressions in the matter of Baal-peor, and by their imperfect fulfillment, at the first, of Moses’ orders in the Midianite war.
