ADONAI said to Moshe and Aharon, "Take handfuls of ashes from a kiln, and let Moshe throw them in the air before Pharaoh's eyes.
They will turn into fine dust over all the land of Egypt and become infected sores on men and animals throughout Egypt."
So they took ashes from a kiln, stood in front of Pharaoh and threw them in the air; and they became infected sores on men and animals.
The magicians couldn't even stand in Moshe's presence because of the sores, which were on them as well as on the other Egyptians.
But ADONAI made Pharaoh hardhearted, so that he didn't listen to them -just as ADONAI had said to Moshe.
