vv. 5-6 Thieves robbed houses and grape pickers stripped vineyards, yet both left a little behind that they did not carry off. However, Yahweh's destruction of Edom would be so complete that nothing at all would remain of her (cf. Jer. 49:9-10). There would be no remnant of Edom left (in contrast to the remnant that Yahweh promised elsewhere to leave in Israel). The form of this assurance sounds like mourning in the presence of death. Concealed treasures of all kinds, human as well as material, would not escape Yahweh's omniscient eye.19
v. 7 Edom's allies would treacherously betray their friend. Thus Edom would not only deceive herself, but her trusted allies would also deceive her. They would do what in the ancient Near East was most despicable, namely, break covenant with a covenant partner (cf. Ps. 55:20; Amos 1:9). Edom's allies would prove to be the worst of enemies. They would fail to assist her in her hour of greatest need. Three parallel descriptions of covenant disloyalty in this verse picture the treachery as certain. Moreover this disloyalty would completely surprise the Edomites.
"Edom was a weak country militarily, its small population and its limited agricultural wealth precluding powerful armed forces. Therefore its ability to attack Judah's Negeb and help plunder Jerusalem had depended on its obsequious alliance with more powerful states, especially Babylon."20
