8The LORD said to Moses and to Aaron, "Take for yourselves a full handful of soot from the kiln, and let Moses scatter it toward the sky before the eyes of Pharaoh."9It shall become dust over all the land of Egypt, and it shall become boils breaking out in blisters on man and on beast throughout all the land of Egypt.10They took the soot of the kiln and stood before Pharaoh, and Moses scattered it toward the sky, and it became boils breaking out in blisters on man and on beast.11And the magicians were not able to stand before Moses because of the boils, for the boils were on the magicians and on all the Egyptians.12The LORD strengthened the heart of Pharaoh, and he did not listen to them, just as the LORD had spoken to Moses.
