"Obadiah's discussion nicely interweaves the themes of divine intervention and human instrumentality."21
v. 8 The repetition of "declares the Lord"(cf. v. 4) reemphasizes Yahweh's initiative in this judgment. "That day"points to a specific, though undefined, day when He would surely destroy Edom.
God would destroy Edom's famous wise men (cf. 1 Kings 4:30; Job 1:1; 2:11; 4:1; Jer. 49:7; Lam. 4:21) and their understanding by allowing them to fail to detect the unfaithfulness of their allies (v. 7) and to overestimate their own security (v. 3).
"Because of its communication with Babylon and Egypt and because of the information gleaned through the caravans going to and from Europe and India, Edom had gained an enviable reputation for wisdom."22
The "mountain of Esau"is Mt. Seir, the mountain God gave Esau and his descendants to inhabit (Deut. 2:5).
v. 9 The "mighty men"of Edom may be a synonym for the wise men (v. 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)23and the region around the town (cf. Gen. 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 end of Edom.
