Zechariah 6:1-8

Now again I looked up, and four chariots were coming out from between two mountains; and the mountains were mountains of [firm, immovable] bronze (divine judgment). The first chariot had red horses (war, bloodshed), the second chariot had black horses (famine, death), [Rev 6:4-6] the third chariot had white horses (victory), and the fourth chariot had strong dappled horses (death through judgment). [Rev 6:2, 8] Then I said to the angel who was speaking with me, “What are these, my lord?” The angel answered me, “These are the four spirits of the heavens, which go out after presenting themselves before the Lord of all the earth, [Ps 104:4; Matt 24:31] with the chariot with the black horses going toward the north country; then the one with the white horses follows after them [because there are two northern powers to overcome], and the chariot with the dappled horses goes toward the south country.” When the strong horses went out, they were eager to patrol the earth. And the LORD said, “Go, patrol the earth.” So they patrolled the earth [watching and protecting it]. Then He called out to me and said to me, “See, those who are going to the north country have quieted My Spirit [of wrath] in the north country.”
