Exodus 9:9-11 ▼

9 It will become fine dust over the entire land of Egypt, and it will become boils breaking out in sores on man and animal in all the land [occupied by the Egyptians].”

10 So they took soot from the kiln, and stood before Pharaoh; and Moses threw it toward the sky, and it became boils erupting in sores on man and animal.

11 The magicians (soothsayer-priests) could not stand before Moses because of the boils, for the boils were on the magicians as well as on all the Egyptians.
