9It shall become fine dust over all the land of Egypt, and become aboils breaking out in sores on man and beast throughout all the land of Egypt.” 10So they took soot from the kiln and stood before Pharaoh. And Moses threw it in the air, and it became boils breaking out in sores on man and beast. 11And bthe magicians could not stand before Moses because of the boils, for the boils came upon the magicians and upon all the Egyptians.
