The Dukes of Edom. Compare Genesis 36:15. By the time that the Israelitesapproached the borders of Edom, the dukes had given place to kings (Numbers 20:14), and everything like abject fear of Israel had passed sway.
The Edomites "came out against Moses with much people and with a strong hand," and refused to allow the Israelites passage through their borders (Numbers 20:20, Numbers 20:21). The mighty men of Moab.
The alarm of the Moabites was indicated by Balak's efforts to induce Balaam to curse the Israelites (Numbers 22-24.). By their "mighty men" some understood men of unusual strength and stature (Cook); but the expression, which is very frequent both in the prophetical and the historical books, seems to be a mere periphrasis for "warriors."
All the inhabitants of Canaan shall melt away. This prophecy received a remarkable accomplishment when "it came to pass that all the kings of the Cannanites heard that the Lord had dried up the waters of Jordan from before the children of Israel, and their heart melted, neither was their spirit in them any more" (Joshua 5:1).
