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.
