Zechariah 6:2-7

6:2 Harnessed to the first chariot were red horses, to the second black horses, 6:3 to the third white horses, and to the fourth spotted horses, all of them strong. 6:4 Then I asked the angelic messenger who was speaking with me, “What are these, sir?” 6:5 The messenger replied, “These are the four spirits of heaven that have been presenting themselves before the Lord of all the earth. 6:6 The chariot with the black horses is going to the north country and the white ones are going after them, but the spotted ones are going to the south country. 6:7 All these strong ones are scattering; they have sought permission to go and walk about over the earth.” The Lord had said, “Go! Walk about over the earth!” So they are doing so.

Revelation 6:4

6:4 And another horse, fiery red, came out, and the one who rode it was granted permission to take peace from the earth, so that people would butcher one another, and he was given a huge sword.

Revelation 19:19-21

19:19 Then I saw the beast and the kings of the earth and their armies assembled to do battle with the one who rode the horse and with his army. 19:20 Now the beast was seized, and along with him the false prophet who had performed the signs on his behalf – signs by which he deceived those who had received the mark of the beast and those who worshiped his image. Both of them were thrown alive into the lake of fire burning with sulfur. 19:21 The others were killed by the sword that extended from the mouth of the one who rode the horse, and all the birds gorged themselves with their flesh.
