Then the dukes of Edom shall be amazed; the mighty men of Moab, trembling shall take hold upon them; all the inhabitants of Canaan shall melt away.

Then were the princes of Edom troubled, trembling seized on the stout men of Moab: all the inhabitants of Chanaan became stiff.

Then the princes of Edom were amazed; The mighty men of Moab, trembling hath seized them; All the inhabitants of Canaan melted away.

Then were the dukes of Edom amazed; The mighty men of Moab, trembling taketh hold upon them: All the inhabitants of Canaan are melted away.

Then have chiefs of Edom been troubled: Mighty ones of Moab, Trembling doth seize them! Melted have all inhabitants of Canaan!

The chiefs of Edom were troubled in heart; the strong men of Moab were in the grip of fear: all the people of Canaan became like water.

Then were the chiefs of Edom affrighted; The mighty men of Moab, trembling taketh hold upon them; All the inhabitants of Canaan are melted away.

Then the chiefs of Edom were dismayed. Trembling takes hold of the leaders of Moab. All the inhabitants of Canaan have melted away.

Then the leaders of Edom were stirred up, and trembling took hold of the robust of Moab. All the inhabitants of Canaan were petrified.

Tunc terrebuntur duces Edom, et robusti Moab: apprehendet eos tremor, dissolventur omnes habitatores Chanann.

The dukes of Edom - See Genesis 36:15. It denotes the chieftains, not the kings of Edom.
The mighty men of Moab - The physical strength and great stature of the Moabites are noted in other passages: see Jeremiah 48:29, Jeremiah 48:41.
Canaan - The name in this, as in many passages of Genesis, designates the whole of Palestine: and is used of course with reference to the promise to Abraham. It was known to the Egyptians, and occurs frequently on the monuments as Pa-kanana, which applies, if not to the whole of Palestine, yet to the northern district under Lebanon, which the Phoenicians occupied and called "Canaan."

The dukes of Edom - Idumea was governed at this time by those called אלפים alluphim, heads, chiefs, or captains. See Clarke's note on Genesis 36:15.

Then the dukes of Edom shall be amazed, Of which there were many, see Genesis 36:15 the land being first governed by dukes, as perhaps it was at this time, though in some few years after it had a king, Numbers 20:14 now these, when they heard of the wonderful things that were done for Israel in Egypt, at the Red sea, and in the wilderness, were astonished and surprised, and filled with fear and dread, see Deuteronomy 2:4,
the mighty men of Moab, trembling shall take hold upon them: as did on Balak the king of Moab, and his people, Numbers 22:2, where may be observed a literal accomplishment of this prophecy:
all the inhabitants of Canaan shall melt away; as their hearts did, through fear, when they heard what God did for Israel against the Egyptians and the Amorites, and understood that they were upon the march to their land to invade it and dispossess them of it: see the fulfilment of this prediction in Joshua 2:9 thus when Babylon shall be destroyed, as Pharaoh and his host were, and the people of God saved out of the midst of her, as Israel was, the kings of the earth will stand afar off for fear of her torment, and bewail and lament for her, Revelation 18:9.

"Then are the princes (alluphim, see Genesis 36:15) of Edom confounded; the mighty men of Moab, trembling seizes them; all the inhabitants of Canaan despair." אלים, like אוּלים in 2-Kings 24:15, scriptio plena for אלים, strong, powerful ones. As soon as these nations should hear of the miraculous guidance of Israel through the Red Sea, and Pharaoh's destruction, they would be thrown into despair from anxiety and alarm, and would not oppose the march of Israel through their land.
