Isaiah 34:5

Heaven. Casting down the rebel angels. (St. Jerome) --- The resolution to destroy the Idumeans, for their cruelty to the Jews, has been taken long ago. All these expressions allude to the last judgment. (Calmet) --- Idumea. Under the name of Idumea or Edom, a people that were enemies of God and his Church. (Challoner) --- Assaradon fell upon Edom two years after Sennacherib's death. (Calmet) --- No strong place like Bosra, shall rescue any from destruction at the last day. (Worthington)
