8. And the Lord said unto Moses and unto Aaron, Let each of you take handfuls of soot from the furnace, and let Moses sprinkle it toward heaven in the sight of Pharaoh.
9. And it shall become dust upon all the land of Egypt, which shall cause boils breaking forth with blisters upon man and upon beast, throughout all the land of Egypt.
10. And they took the soot of the furnace and stood before Pharaoh; and Moses sprinkled it up toward heaven; and boils breaking forth with blisters came upon man and upon beast
11. until the magicians could not stand before Moses because of the boils; for the boils were upon the magicians, and upon all the Egyptians.
12. And the Lord hardened the heart of Pharaoh, and he did hearken unto them as the Lord had spoken unto Moses.
13. Then the Lord said unto Moses, Rise up early in the morning and stand before Pharaoh and say unto him, Thus saith the Lord God of the Hebrews, Let my people go that they may serve me.
14. For otherwise this time I will send all my plagues upon thine heart and upon thy slaves and upon thy people that thou may know that there is none like me in all the earth.
15. For now I will stretch out my hand that I may smite thee and thy people with pestilence, and thou shalt be cut off from the earth.
16. For in truth I have placed thee to declare my power in thee, and that my name may be declared throughout all the earth.
17. Thou even so dost exalt thyself against my people that thou wilt not let them go.
18. Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the foundation thereof even until now.
