10. And they took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward heaven; and it became boils breaking forth with sores upon man, and upon beast.
11. And 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 hearkened not unto them; as the LORD had spoken unto Moses.
13. And the LORD said unto Moses,
14. For I will at this time send all my plagues upon your heart, and upon your servants, and upon your people; that you 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 you and your people with pestilence; and you shall be cut off from the earth.
16. And indeed for this very cause have I raised you up, to show in you my power; and that my name may be declared throughout all the earth.
