The appearance of them is as the appearance of horses. They arc said to resemble horses in the shape of the head; hence the Germans call them Heupferde, or hay-horses, and the Italians cavalette. This resemblance had been noticed long ago by Theodoret, who says, "If any one should examine accurately the head of the locust, he will find it exceedingly like that of a horse."
And as horsemen, so shall they run. In rapidity of motion they resembled running horses (parashim). Like the noise of chariots on the tops of mountains shall they leap. This is the next circumstance noticed about them, viz.
the noise of their motion. Their motion was peculiar; it was springing or leaping, and, when they sprang or leaped, the noise they made resembled the rattling of a jerky two-wheeled war-chariot over a rough mountain-road.
