'Horses' in the Bible

I have sent among you pestilence by the way of Egypt, I have slain by sword your choice ones, With your captive horses, And I cause the stink of your camps to come up -- even into your nostrils, And ye have not turned back unto Me, An affirmation of Jehovah.

Do horses run on a rock? Doth one plough it with oxen? For ye have turned to gall judgment, And the fruit of righteousness to wormwood.
