And I lifted up mine eyes again, and saw, 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, strong horses.
