⁸Then the LORD said to Moses and Aaron, “Take handfuls of soot from the furnace; in the sight of Pharaoh, Moses is to toss it into the air. ⁹It will become fine dust over all the land of Egypt, and festering boils will break out on man and beast throughout the land.” ¹⁰So they took soot from the furnace and stood before Pharaoh. Moses tossed it into the air, and festering boils broke out on man and beast. ¹¹The magicians could not stand before Moses, because the boils had broken out on them and on all the Egyptians. ¹²But the LORD hardened Pharaoh’s heart, and he would not listen to them, just as the LORD had said to Moses.
