Zechariah 6:4

Again I lifted up my eyes, and saw, and behold, four chariots came out from between two mountains; and the mountains were mountains of bronze.

In the first chariot were red horses. In the second chariot were black horses.

In the third chariot were white horses. In the fourth chariot were dappled horses, all of them powerful.

The angel answered me, “These are the four winds of the sky, which go out from standing before the Lord of all the earth.

The one with the black horses goes out toward the north country; and the white went out after them; and the dappled went out toward the south country.”

The strong went out, and sought to go that they might walk back and forth through the earth. He said, “Go around and through the earth!” So they walked back and forth through the earth.
