Thematic Bible: Of the mountains and chariots

And I turned and lifted up my eyes and looked, and, behold, there came four chariots out from between two mountains, and those mountains were of brass. In the first chariot were red horses and in the second chariot black horses; in the third chariot white horses and in the fourth chariot grisled and bay horses. read more.
Then I answered and said unto the angel that talked with me, What is this, my lord? And the angel answered and said unto me, These are the four spirits of the heavens, which go forth from standing before the Lord of all the earth. The one with the black horses went forth towards the north country, and the white went forth after them, and the grisled went forth toward the south country. And the bay went forth and sought to go that they might walk to and fro through the earth, and he said, Go from here; walk to and fro through the earth. So they walked to and fro through the earth. Then he called me and spoke unto me, saying, Behold, those that went toward the north country have quieted my spirit in the north country.
