Daniel 2:38-40   38. And wheresoever the children of men dwell, the beasts of the field and the fowls of the heaven hath he given into thine hand, and hath made thee ruler over them all. Thou art this head of gold. 39. And after thee shall arise another kingdom inferior to thee, and another third kingdom of brass, which shall bear rule over all the earth. 40. And the fourth kingdom shall be strong as iron: forasmuch as iron breaketh in pieces and subdueth all things: and as iron that breaketh all these, shall it break in pieces and bruise.

Zechariah 6:1-8   1. And I turned, and lifted up mine eyes, and looked, and, behold, there came four chariots out from between two mountains; and the mountains were mountains of brass. 2. In the first chariot were red horses; and in the second chariot black horses; 3. And in the third chariot white horses; and in the fourth chariot grisled and bay horses. 4. Then I answered and said unto the angel that talked with me, What are these, my lord? 5. 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. 6. The black horses which are therein go forth into the north country; and the white go forth after them; and the grisled go forth toward the south country. 7. And the bay went forth, and sought to go that they might walk to and fro through the earth: and he said, Get you hence, walk to and fro through the earth. So they walked to and fro through the earth. 8. Then cried he upon me, and spake unto me, saying, Behold, these that go toward the north country have quieted my spirit in the north country.
