“Yahweh said to Moses and Aaron, ‘Take for yourselves handfuls of soot from the kiln and let Moses hurl it heavenward before Pharoah’s eyes. It will become dust over the entire land of Egypt, and it will become boils erupting into sores on man and beast throughout the land of Egypt. So they took soot of the kiln and stood in front of Pharaoh, and Moses threw it heavenward; and it became boils and sores, erupting on man and beast . . . Yahweh hardened the heart of Pharaoh and he did not heed them, as Yahweh had already foretold to Moses” (Ex 9:8-12).
