Matthew saith an ass and a colt. The other evangelists speak only of the colt. The heathens, by a light of nature showing them there was a reverence and honour due to the Divine Being, were wont, in the use they made of creatures for any Divine service, to use such as they had not before used for common uses: the Philistines, 1 Samuel 6:7, sending home the ark, set it on a new cart, and took two milch kine on which there never came yoke. But our Saviour probably made choice of such a colt for the further notice of the miracle, (colts being when first backed more unruly), or for some other wise end which we know not.
