Thematic Bible: Of boils and open sores

Then said Yahweh unto Moses and unto Aaron, Take you your hands full of the ashes of an oven, - and Moses shall scatter them towards the heavens, before the eyes of Pharaoh: then shall they become fine dust, over all the land of Egypt, - and shall become on man and on beast, a burning sore, breaking out in pustules in all the land of Egypt. So they took the ashes of an oven and stood before Pharaoh, and Moses scattered them towards the heavens, - and it came to pass that there was a burning sore in pustules breaking out, among men, and among beasts; read more.
and the sacred scribes could not stand before Moses, because of the burning sore, - for the burning sore had come on the sacred scribes, and on all the Egyptians. But Yahweh let the heart of Pharaoh wax bold, and he hearkened not unto them, - as spake Yahweh unto Moses.
