10. 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.
11. The magicians could not stand before Moses, because all the Egyptians had boils, even the magicians.
12. But the Lord made the king stubborn, so he refused to listen to Moses and Aaron, just as the Lord had said.
13. Then the Lord said to Moses, “Get up early in the morning and go to the king of Egypt. Tell him, ‘This is what the Lord, the God of the Hebrews, says: Let my people go to worship me.
14. If you don’t, this time I will punish you, your officers, and your people, with all my power. Then you will know there is no one in the whole land like me.
15. By now I could have used my power and caused a terrible disease that would have destroyed you and your people from the earth.
16. But I have let you live for this reason: to show you my power so that my name will be talked about in all the earth.
17. You are still against my people and do not want to let them go.
18. So at this time tomorrow, I will send a terrible hailstorm, the worst in Egypt since it became a nation.
