Hast thou given the horse strength? hast thou clothed his neck with thunder?
That is, given him courage? which is meant by neighing and shaking his neck.
He paweth in the valley, and rejoiceth in strength: he goeth on to meet the armed men.
He beats with his hoof.
He swalloweth the ground with fierceness and rage: neither believeth he the sound of the trumpet.
He so rides the ground that it seems nothing under him.

- Job 39:19
