Obadiah 1:8

Shall I not in that day, saith the Lord, even destroy the wise men out of Edom ,.... When they shall be invaded by the enemy, and treacherously dealt with by their allies; so that there shall be no wise counsellors at court to give advice what proper methods should be taken at such a season; they should either be taken off by death, or their wisdom should be turned into folly, and they be rendered incapable of giving right counsel:

and understanding out of the mount of Esau ? that is, men of understanding, as the Targum, should be destroyed out of Edom or Idumea, which was a mountainous country; such as were well versed in politics, or understood military affairs, and how to conduct at such a critical time; to form schemes, and concert measures, and wisely put them in execution; and to be deprived of all such must be a great loss at such a time, and add to their distress and calamity; see Jeremiah 49:7 .
