Isaiah 63:2
1 Who is this who comes from Edom, dressed in bright red, coming from Bozrah? Who is this one wearing royal attire, who marches confidently because of his great strength? “It is I, the one who announces vindication, and who is able to deliver!” 2 Why are your clothes red? Why do you look like someone who has stomped on grapes in a vat? 3 “I have stomped grapes in the wine press all by myself; no one from the nations joined me. I stomped on them in my anger; I trampled them down in my rage. Their juice splashed on my garments and stained all my clothes. 4 For I looked forward to the day of vengeance, and then payback time arrived. 5 I looked, but there was no one to help; I was shocked because there was no one offering support. So my right arm accomplished deliverance; my raging anger drove me on. 6 I trampled nations in my anger; I made them drunk in my rage; I splashed their blood on the ground.”
Revelation 19:13
11 Then I saw heaven opened and here came a white horse! The one riding it was called “Faithful” and “True,” and with justice he judges and goes to war. 12 His eyes are like a fiery flame and there are many diadem crowns on his head. He has a name written that no one knows except himself. 13 He is dressed in clothing dipped in blood, and he is called the Word of God. 14 The armies that are in heaven, dressed in white, clean, fine linen, were following him on white horses. 15 From his mouth extends a sharp sword so that with it he can strike the nations. He will rule them with an iron rod, and he stomps the winepress of the furious wrath of God, the All-Powerful. 16 He has a name written on his clothing and on his thigh: “King of kings and Lord of lords.”
Notes and References
"... The garments of God were stained with the blood of the winepress in Isaiah 63:2-3, when God was avenging his servants by judgment (compare Revelation 14:17-20); a later Jewish tradition naturally connects this text with the idea of Genesis 49:10-11, reading the latter as proclaiming that the warrior Messiah will be stained with blood. Compare Wisdom of Solomon 18:15-16, where God’s slaying the firstborn of Egypt is figuratively described as his Word leaping out of heaven like a mighty warrior; his commandment goes forth as a sharp sword (compare Revelation 19:15) ..."
