Exodus 9:8-10

The Sixth Blow: Boils

9:8 Then the Lord said to Moses and Aaron, “Take handfuls of soot from a furnace, and have Moses throw it into the air while Pharaoh is watching. 9:9 It will become fine dust over the whole land of Egypt and will cause boils to break out and fester on both people and animals in all the land of Egypt.” 9:10 So they took soot from a furnace and stood before Pharaoh, Moses threw it into the air, and it caused festering boils to break out on both people and animals.
