Exodus 9:1 Then the LORD said to Moses, “Go in to Pharaoh and say to him, ‘Thus says the LORD, the God of the Hebrews, “Let my people go, that they may serve me. For if you refuse to let them go and still hold them, behold, the hand of the LORD will fall with a very severe plague upon your livestock that are in the field, the horses, the donkeys, the camels, the herds, and the flocks. But the LORD will make a distinction between the livestock of Israel and the livestock of Egypt, so that nothing of all that belongs to the people of Israel shall die.”’” And the LORD set a time, saying, “Tomorrow the LORD will do this thing in the land.” And the next day the LORD did this thing. All the livestock of the Egyptians died, but not one of the livestock of the people of Israel died. And Pharaoh sent, and behold, not one of the livestock of Israel was dead. But the heart of Pharaoh was hardened, and he did not let the people go.
Moses told Pharaoh that the Israelites would be spared, and Pharaoh believed it enough to confirm this. Nevertheless, he did not change his heart when it was proven that Moses and his God were exactly right. (Guzik)
God will have Israel released, Pharaoh opposes it, and the trial is, whose word shall stand. The hand of the Lord at once is upon the cattle, many of which, some of all kinds, die by God’s own hand. This was greatly to the loss of the owners; they had made Israel poor, and now God would make them poor. The hand of God is to be seen, even in the sickness and death of cattle; for a sparrow falls not to the ground without our Father. None of the Israelites’ cattle should die; the Lord shall sever. The cattle died. The Egyptians worshipped their cattle. What we make an idol of, it is just with God to remove from us. This proud tyrant and cruel oppressor deserved to be made an example by the just Judge of the universe. None who are punished according to what they deserve, can have any just cause to complain. Hardness of heart denotes that state of mind upon which neither threatenings nor promise, neither judgements nor mercies, make any abiding impression. The conscience being stupified, and the heart filled with pride and presumption, they persist in unbelief and disobedience. (Henry)
Then the Lord said unto Moses,…. The same day the plague of the flies was removed: go in unto Pharaoh boldly, without any fear of him or his court: and tell him, thus saith the Lord God of the Hebrews: speak in the name of Jehovah, the God whom the Hebrews worship, and who owns them for his people, and has a special love for them, and takes a special care of them, and is not ashamed to be called their God, as poor and as oppressed as they be: let my people go, that they may serve me; this demand had been often made, and, though so reasonable, was refused. (Gill)
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. (Brown)
Many today, like Pharaoh, deny God and His control over all there is. They deny Him as Creator and author of life and all things created. They deny not only the honor and glory and praise and worship due Him but throw aside His grace, mercy, and love. What man can stand on the day of judgment and deny God then? What will a man say when they bow before Him and are cast into the lake of fire that burns forever and ever, where there is no death but continual torment for eternity? We have all been given free will to choose to honor and glorify God with our thoughts, words, and actions. Giving God a casual nod once or twice per week is not honoring and glorifying Him. No, it is deceiving yourself to think it is acceptable worship of the Heavenly Creator, All-Mighty, All-Knowing, Ever-Present, and All-Powerful God. You will do well to examine your heart for its intentions. Are they focused on things of this world and what pleases their fleshly desires? God is not to be mocked by complacency, neglect, or denial. Repent and take hold of His free gift of salvation through Jesus Christ.
