'Horses' in the Bible

I have seen by night, and lo, one riding on a red horse, and he is standing between the myrtles that are in the shade, and behind him are horses, red, bay, and white.

In the first chariot are red horses, and in the second chariot brown horses,

and in the third chariot white horses, and in the fourth chariot strong grisled horses.

The brown horses that are therein, are coming forth unto the land of the north; and the white have come forth unto their hinder part; and the grisled have come forth unto the land of the south;

And they have been as heroes, Treading in mire of out-places in battle, And they have fought, for Jehovah is with them, And have put to shame riders of horses.
