'Boils' in the Bible

It shall become small dust over all the land of Egypt, and shall be a boil breaking forth with boils 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 a boil breaking forth with boils 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.
