Have you given the horse his strength?

“Have you given the horse strength?
Have you clothed his neck with thunder?
 Can you frighten him like a locust?
His majestic snorting strikes terror.
He paws in the valley, and rejoices in his strength;
He gallops into the clash of arms.
He mocks at fear, and is not frightened;
Nor does he turn back from the sword.
The quiver rattles against him,
He devours the distance with fierceness and rage;
Nor does he come to a halt because the trumpet has sounded.

At the blast of the trumpet he says, ‘Aha!’
He smells the battle from afar,
The thunder of captains and shouting."
