Obadiah1chapter 1

Edom's country was a natural fortress and the book keeps saying so. The highlands south-east of the Dead Sea rise steeply from the rift valley, cut by narrow gorges, with settlements perched on sandstone crags reached by a single defensible path. The line about dwelling in the clefts of the rock and saying who will bring me down is a description of the terrain, not an insult invented for the occasion.

The wealth came from position. The King's Highway, the main north-south caravan route between Arabia and Damascus, ran through Edomite territory, and controlling it meant taxing spices, incense, and metals. Edom also had copper — the mines and smelting sites in the Wadi Arabah were worked for centuries.

Teman, named for its wisdom, was a district of Edom, and the region's reputation for wise men shows up elsewhere in Scripture; Job's friend Eliphaz is called a Temanite. The taunt that God will destroy the wise men out of Edom is aimed at a genuine local point of pride.

The relationship is the wound. Edom descended from Esau, Jacob's twin brother, which makes every line about your brother Jacob literal family language. Standing aside on the day strangers carried off his wealth, cutting down the fugitives at the crossroads, and handing over survivors were the acts of a relative, not an enemy.
