Obadiah 1:9

The "mighty men" of Edom may be a synonym for the wise men (Obadiah 1:8) or the nation’s warriors. Together with the wise men, the mighty men form a merism, a figure of speech in which two parts stand for the whole, in this case all the Edomites. Rather than feeling confident, the mighty men, a chief resource of the nation, would feel dismayed when they realized that their covenant partners had proved traitorous.

Teman was both a prominent town in central Edom (possibly modern Tuwilan) [Note: Yohanan Aharoni and Michael Avi-Yonah, The Macmillan Bible Atlas, map 155; Student Map Manual: Historical Geography of the Bible Lands, map 9-2.] and the region around the town (cf. Genesis 36:10-11). But its name stands for the whole nation (by metonymy). The end of all this deception and destruction would be the total termination of Edom.
