Zechariah 6:2-7
2 The first chariot had red horses, the second black,
3 the third white, and the fourth dappled—all of them powerful.
4 I asked the angel who was speaking to me, “What are these, my lord?”
5 The angel answered me, “These are the four spirits of heaven, going out from standing in the presence of the Lord of the whole world.
6 The one with the black horses is going toward the north country, the one with the white horses toward the west, and the one with the dappled horses toward the south.”
7 When the powerful horses went out, they were straining to go throughout the earth. And he said, “Go throughout the earth!” So they went throughout the earth.
