Exodus 9:1-12

Then the LORD told Moses, “Go to the king of Egypt and tell him, ‘This is what the LORD, the God of the Hebrews, says: Let my people go to worship me. If you refuse to let them go and continue to hold them, the LORD will punish you. He will send a terrible disease on your farm animals that are in the fields. He will cause your horses, donkeys, camels, cattle, goats, and sheep to become sick. But the LORD will treat Israel’s animals differently from the animals of Egypt. None of the animals that belong to the Israelites will die. The LORD has set tomorrow as the time he will do this in the land.’ ” The next day the LORD did as he promised. All the farm animals in Egypt died, but none of the animals belonging to Israelites died. The king sent people to see what had happened to the animals of Israel, and they found that not one of them had died. But the king was still stubborn and did not let the people go. The LORD said to Moses and Aaron, “Fill your hands with ashes from a furnace. Moses, throw the ashes into the air in front of the king of Egypt. The ashes will spread like dust through all the land of Egypt. They will cause boils to break out and become sores on the skin of people and animals everywhere in the land.” So Moses and Aaron took ashes from a furnace and went and stood before the king. Moses threw ashes into the air, which caused boils to break out and become sores on people and animals. The magicians could not stand before Moses, because all the Egyptians had boils, even the magicians. But the LORD made the king stubborn, so he refused to listen to Moses and Aaron, just as the LORD had said.
