91 Then the Lord said to Moses, "Go in to Pharaoh and tell him, 'Thus says the Lord God of the Hebrews: "Let My people go, that they may serve Me. 2 For if you refuse to let them go, and still hold them, 3 behold, the hand of the Lord will be on your cattle in the field, on the horses, on the donkeys, on the camels, on the oxen, and on the sheep--a very severe pestilence. 4 And the Lord will make a difference between the livestock of Israel and the livestock of Egypt. So nothing shall die of all that belongs to the children of Israel." ' " 5 Then the Lord appointed a set time, saying, "Tomorrow the Lord will do this thing in the land." 6 So the Lord did this thing on the next day, and all the livestock of Egypt died; but of the livestock of the children of Israel, not one died. 7 Then Pharaoh sent, and indeed, not even one of the livestock of the Israelites was dead. But the heart of Pharaoh became hard, and he did not let the people go.
8 So the Lord said to Moses and Aaron, "Take for yourselves handfuls of ashes from a furnace, and let Moses scatter it toward the heavens in the sight of Pharaoh. 9 And it will become fine dust in all the land of Egypt, and it will cause boils that break out in sores on man and beast throughout all the land of Egypt." 10 Then they took ashes from the furnace and stood before Pharaoh, and Moses scattered them toward heaven. And they caused boils that break out in sores on man and beast. 11 And the magicians could not stand before Moses because of the boils, for the boils were on the magicians and on all the Egyptians. 12 But the Lord hardened the heart of Pharaoh; and he did not heed them, just as the Lord had spoken to Moses.
13 Then the Lord said to Moses, "Rise early in the morning and stand before Pharaoh, and say to him, 'Thus says the Lord God of the Hebrews: "Let My people go, that they may serve Me, 14 for at this time I will send all My plagues to your very heart, and on your servants and on your people, that you may know that there is none like Me in all the earth.

Commentary on Exodus 9:1-7
(Read Exodus 9:1-7)
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 a sort of murrain. 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. This state of mind is also called the stony heart. Very different is the heart of flesh, the broken and contrite heart. Sinners have none to blame but themselves, for that pride and ungodliness which abuse the bounty and patience of God. For, however the Lord hardens the hearts of men, it is always as a punishment of former sins.
Commentary on Exodus 9:8-12
(Read Exodus 9:8-12)
When the Egyptians were not wrought upon by the death of their cattle, God sent a plague that seized their own bodies. If lesser judgments do not work, God will send greater. Sometimes God shows men their sin in their punishment. They had oppressed Israel in the furnaces, and now the ashes of the furnace are made a terror to them. The plague itself was very grievous. The magicians themselves were struck with these boils. Their power was restrained before; but they continued to withstand Moses, and to confirm Pharaoh in his unbelief, till they were forced to give way. Pharaoh continued obstinate. He had hardened his own heart, and now God justly gave him up to his own heart's lusts, permitting Satan to blind and harden him. If men shut their eyes against the light, it is just with God to close their eyes. This is the sorest judgment a man can be under out of hell.
Commentary on Exodus 9:13-21
(Read Exodus 9:13-21)
Moses is here ordered to deliver a dreadful message to Pharaoh. Providence ordered it, that Moses should have a man of such a fierce and stubborn spirit as this Pharaoh to deal with; and every thing made it a most signal instance of the power of God has to humble and bring down the proudest of his enemies. When God's justice threatens ruin, his mercy at the same time shows a way of escape from it. God not only distinguished between Egyptians and Israelites, but between some Egyptians and others. If Pharaoh will not yield, and so prevent the judgment itself, yet those that will take warning, may take shelter. Some believed the things which were spoken, and they feared, and housed their servants and cattle, and it was their wisdom. Even among the servants of Pharaoh, some trembled at God's word; and shall not the sons of Israel dread it? But others believed not, and left their cattle in the field. Obstinate unbelief is deaf to the fairest warnings, and the wisest counsels, which leaves the blood of those that perish upon their own heads.
