Amos next moved from addressing chief cities to addressing countries, specifically countries with closer ethnic ties to the Israelites. Perhaps their closer relationship to Israel is why he mentioned countries rather than cities in the introductions to the later oracles. Edom's overflowing sin that brought divine wrath down on its people was the way the Edomites had treated the Israelites. The Edomites had been very hostile to their "brother,"Israel (cf. Gen. 25:29-30; Num. 20:14; Deut. 2:4; 23:7; Obad. 12). This hostility existed throughout the history of these two nations. This animosity even led the Edomites to attack the Israelites with the sword (cf. Obad. 10). Consequently God would send destruction on Edom's chief southern and northern cities (or districts), even on the whole land (a merism). The Assyrians subjugated Edom in the eighth century B.C., and the Nabateans, an Arabian tribe, took it over in the fourth century B.C.
