The unicorns, symbolizing the Idumeans, will perish alongside them, and the land will absorb their lifeblood. The streams will become like tar, and the earth itself will transform into a sea of pitch. Birds will come to inhabit this place; owls and ravens will make their nests there. Spirits of chaos will descend, and nightmares will find their abode in this desolate land, having secured their resting places (Is. 34:7, 9, 11, 14). The afflictions foretold by the prophet will indeed descend upon Idumea following its prophesied ruin; rather than people, creatures like birds, hedgehogs, and vultures will make their homes in the forsaken dwellings of Idumea.
