Pulpit Comm: "Coming as King, he could not walk undistinguished among the crowd; he must ride. But to mount a war horse would denote that he was leader of an army or a worldly potentate; so he rides upon an ass, an animal used by the judges of Israel, and chieftains on peaceful errands (Judges 5:10; Judges 10:4); one, too, greatly valued, and often of stately appearance in Palestine. And (καὶ) a colt the foal of an ass; such as she asses bear, and one not trained. "
