Who is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save. Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winefat? I have trodden the winepress alone; and of the people there was none with me: for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment. For the day of vengeance is in mine heart, and the year of my redeemed is come. And I looked, and there was none to help; and I wondered that there was none to uphold: therefore mine own arm brought salvation unto me; and my fury, it upheld me. And I will tread down the people in mine anger, and make them drunk in my fury, and I will bring down their strength to the earth.
When the Lord returns to set up His kingdom, He must first destroy His enemies. That destruction takes place at different times and in different places – one stage occurs in the Valley of Armageddon, Revelation 16:16, another in the Valley of Jehoshaphat, Joel 3:12, and another in Edom. The latter is what Isaiah spoke about here. The Messiah is marching up from Bozrah, a metropolis of Edom, in glorious garments that are red with the blood of Israel’s foes. When asked why His apparel is red, He uses the figure of a winepress to describe His trampling of His enemies. The time had come for Him to wreak vengeance on them and to redeem His people. In the absence of any merely human deliverer, He stepped in and won the victory.
