Exodus 9:9-11

New International Version

⁹ It will become fine dust over the whole land of Egypt, and festering boils^(A) will break out on people and animals throughout the land.”

¹⁰ So they took soot from a furnace and stood before Pharaoh. Moses tossed it into the air, and festering boils broke out on people and animals. ¹¹ The magicians^(B) could not stand before Moses because of the boils that were on them and on all the Egyptians.
