יהוה said to Moses and to Aaron, “Take handfuls of ashes of the furnace, and let Moses sprinkle it toward the sky in the sight of Pharaoh. It shall become small dust over all the land of Egypt, and shall be a boils and blisters breaking out on man and on animal, throughout all the land of Egypt.” They took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward the sky; and it became boils and blisters breaking on man and on animal. The magicians couldn’t stand before Moses because of the boils; for the boils were on the magicians and on all the Egyptians. יהוה hardened the heart of Pharaoh, and he didn’t listen to them, as יהוה had spoken to Moses.
