Zechariah 6:5 (KJV)

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.

In the first chariot were red horses; and in the second chariot black horses;

And in the third chariot white horses; and in the fourth chariot grisled and bay horses.

Then I answered and said unto the angel that talked with me, What are these, my lord?

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.

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.

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.

And the word of the LORD came unto me, saying,

Take of them of the captivity, even of Heldai, of Tobijah, and of Jedaiah, which are come from Babylon, and come thou the same day, and go into the house of Josiah the son of Zephaniah;
