Isaiah 34:5-7

5-7. For my sword Poetical instrument of vengeance, and its use an ethical necessity against conscious wrong doers.

Be bathed Or, made drunk, (Septuagint and Vulgate;) a figure from Deuteronomy 32:42, and kept up in Revelation, from wine of the wrath of God.

In heaven The seat of the divine plans upon Idumaea, or Edom, representatively, used for all peoples and nations warring against Jehovah’s cause. Nothing can expiate their crimes of incorrigible rebellion but their sacrifice. As all sin requires this, through use of the blood and fat of victims, so Edom, in one of its chief localities, Bozrah, for example, situated in its eastern hills, (not the “Bozrah” of the north, in the Hauran,) shall witness a great sacrificial slaughter, thorough, final, making clean sweep of men and animals, even wild, fierce, strong, young and old animals, all representing every class of men ranked among God’s potent and malignant foes.

Unicorns Is of doubtful meaning. Delitzsch and Gesenius translate it buffalo; Bochart, gazelle. Neither is satisfactory. The original word, R’em, means a roaring, untamed animal of great strength and fierceness, and answers as much to wild bull (possibly buffalo bull) as to any thing else which present knowledge of the ancient natural history in of Palestine can supply. The rhinoceros may have rarely touched that territory in the warm jungles of the Ghor near the Dead Sea, but of this there is no other knowledge than what is possibly implied in the word itself. All these go down together, and in this way does Jehovah avenge Edom, a people figuratively comprehending all his enemies.
