And יהוה said to Mosheh and Aharon, “Fill your hands with ashes from a furnace and let Mosheh scatter it toward the heavens before the eyes of Pharaoh.
And יהוה said to Mosheh, “Say to Aharon, ‘Stretch out your rod, and strike the dust of the land, so that it becomes gnats in all the land of Mitsrayim.’ ”
So they took ashes from the furnace and stood before Pharaoh, and Mosheh scattered them toward the heavens. And they caused boils, breaking out in sores on man and beast.
“And it shall become fine dust in all the land of Mitsrayim, and it shall cause boils that break out in sores on man and beast in all the land of Mitsrayim.”
