5 For my sword is bathed in the heavens; behold, it shall come down upon Edom, and upon the people of my ban, to judgment. 6 The sword of Jehovah is filled with blood, it is made fat with fatness, with the blood of lambs and goats, with the fat of the kidneys of rams; for Jehovah hath a sacrifice in Bozrah, and a great slaughter in the land of Edom. 7 And the buffaloes shall come down with them, and the bullocks with the bulls; and their land shall be soaked with blood, and their dust made fat with fatness. 8 For it is the day of Jehovah's vengeance, the year of recompenses for the controversy of Zion.
Matthew Henry's Commentary on Isaiah 34:5-8
Commentary on Isaiah 34:1-8
(Read Isaiah 34:1-8)
Here is a prophecy of the wars of the Lord, all which are both righteous and successful. All nations are concerned. And as they have all had the benefit of his patience, so all must expect to feel his resentment. The description of bloodshed suggests tremendous ideas of the Divine judgments. Idumea here denotes the nations at enmity with the church; also the kingdom of antichrist. Our thoughts cannot reach the horrors of that awful season, to those found opposing the church of Christ. There is a time fixed in the Divine counsels for the deliverance of the church, and the destruction of her enemies. We must patiently wait till then, and judge nothing before the time. Through Christ, mercy is exercised to every believer, consistently with justice, and his name is glorified.
