Edom
'Edom' or 'Idumea,' as in Isaiah 34:5, signifies people who are in evil and falsities derived there.

Zephaniah 2:9-10
9
Therefore as I live, says Yahweh of Armies, the God of Israel, surely Moab will be as Sodom, and the children of Ammon as Gomorrah, a possession of nettles, and salt pits, and a perpetual desolation. The remnant of my people will plunder them, and the survivors of my nation will inherit them.
10
This they will have for their pride, because they have reproached and magnified themselves against the people of Yahweh of Armies.
