Therefore hear the counsel of the LORD, that he hath taken against Edom; and his purposes, that he hath purposed against the inhabitants of Teman: Surely the least of the flock shall draw them out: surely he shall make their habitations desolate with them. The inhabitants of Teman - Taken here for the whole of Idumea. These are a kind of synonyms which prevent monotony, and give variety to the poet's versification.
Surely the least or the flock shall draw them out - They shall be like timid sheep; the weakest foe shall overcome them.
