'Horses' in the Bible

I saw by night, and behold a man riding upon a red horse, and he stood among the myrtle trees that were in the bottom; and behind him were there red horses, speckled, and white.

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.

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 they shall be as mighty men, which tread down their enemies in the mire of the streets in the battle: and they shall fight, because the LORD is with them, and the riders on horses shall be confounded.

In that day shall there be upon the bells of the horses, HOLINESS UNTO THE LORD; and the pots in the LORD'S house shall be like the bowls before the altar.
