The LORD says he will destroy the wise men out of Edom and remove understanding from Mount Esau (Obadiah 1:8). Obadiah also says Edom’s mighty men will be dismayed, and everyone from Mount Esau will be cut off by slaughter (Obadiah 1:9).
In Obadiah 1:8–9, Yahweh announces a coming “day” when Edom will lose what it trusts most: insight and strength. Wisdom and understanding will be removed from Edom’s hill country, called the mountain of Esau. Then the fighting men—addressed through Teman—will be shaken and demoralized. These lines sit inside Obadiah’s opening announcement of judgment on Edom. Just before this, Edom is portrayed as being deceived by alliances and by a sense of safety in its strong positions (Obad.1.7).
Obadiah 1:8–9 presents Yahweh as the direct actor in Edom’s collapse. The passage ties Edom’s downfall to the removal of what usually keeps a nation stable: capable counsel (“wise men” and “understanding”) and military strength (“mighty men”). The text also frames the outcome as sweeping and violent.
