For the Edomites’ stubborn refusal to aid Israel , first during the time of wilderness wandering (Numbers 20:14 -21) and later during a time of invasion (2 Chronicles 21), they are roundly condemned by the prophet Obadiah.
Obadiah describes their crimes, tries their case, and pronounces their judgment: total destruction. Consider Obadiah and see Jehovah pronounce judgment on Edom because of their indifference to and defiance of God, their cowardice and pride, and their treachery toward their brothers in Judah .
