3-5. Behold, the hand of the Lord is upon thy cattle—A fifth application was made to Pharaoh in behalf of the Israelites by Moses, who was instructed to tell him that, if he persisted in opposing their departure, a pestilence would be sent among all the flocks and herds of the Egyptians, while those of the Israelites would be spared. As he showed no intention of keeping his promise, he was still a mark for the arrows of the Almighty's quiver, and the threatened plague of which he was forewarned was executed. But it is observable that in this instance it was not inflicted through the instrumentality or waving of Aaron's rod, but directly by the hand of the Lord, and the fixing of the precise time tended still further to determine the true character of the calamity (Jer 12:4).

     6. all the cattle of Egypt died—not absolutely every beast, for we find (Ex 9:19, 21) that there were still some left; but a great many died of each herd—the mortality was frequent and widespread. The adaptation of this judgment consisted in Egyptians venerating the more useful animals such as the ox, the cow, and the ram; in all parts of the country temples were reared and divine honors paid to these domesticated beasts, and thus while the pestilence caused a great loss in money, it also struck a heavy blow at their superstition.

     7. Pharaoh sent . . . there was not one of the cattle of the Israelites dead—The despatch of confidential messengers indicates that he would not give credit to vague reports, and we may conclude that some impression had been made on his mind by that extraordinary exemption, but it was neither a good nor a permanent impression. His pride and obstinacy were in no degree subdued.
