8. The Lord said to Moses and Aaron, Take handfuls of ashes or soot from the brickkiln and let Moses sprinkle them toward the heavens in the sight of Pharaoh.
9. And it shall become small dust over all the land of Egypt, and become boils breaking out in sores on man and beast in all the land [occupied by the Egyptians].
10. So they took ashes or soot of the kiln and stood before Pharaoh; and Moses threw them toward the sky, and it became boils erupting in sores on man and beast.
11. And the magicians could not stand before Moses because of their boils; for the boils were on the magicians and all the Egyptians.
12. But the Lord hardened the heart of Pharaoh, making it strong and obstinate, and he did not listen to them or heed them, just as the Lord had told Moses.
13. Then the Lord said to Moses, Rise up early in the morning and stand before Pharaoh and say to him, Thus says the Lord, the God of the Hebrews, Let My people go, that they may serve Me.
14. For this time I will send all My plagues upon your heart and upon your servants and your people, that you may recognize and know that there is none like Me in all the earth.
15. For by now I could have put forth My hand and have struck you and your people with pestilence, and you would have been cut off from the earth.
16. But for this very purpose have I let you live, that I might show you My power, and that My name may be declared throughout all the earth. [Rom. 9:17-24.]
17. Since you are still exalting yourself [in haughty defiance] against My people by not letting them go,
18. Behold, tomorrow about this time I will cause it to rain a very heavy and dreadful fall of hail, such as has not been in Egypt from its founding until now.
