“The Lord said to Moses and to Aaron: Take for you handfuls of soot of the furnace, and Moses will throw it heavenward before the eyes of Pharaoh” (Exodus 9:8). “The Lord said to Moses and to Aaron: Take for you handfuls of soot of the furnace” – a great miracle was performed with the boils, as both Moses and Aaron took their handfuls, and Moses’s hand held his handful and Aaron’s handful; from here, a small area can have a large capacity.6If God wills it.
This plague came upon them through the Holy One blessed be He, Moses, and Aaron, as both Moses and Aaron took the soot of the furnace, and Moses threw it heavenward, and the Holy One blessed be He transformed it into boils above, and it fell upon them. “It will become dust over the entire land of Egypt, and will be boils erupting into blisters upon man and upon animal, throughout the land of Egypt” (Exodus 9:9).
“It will become dust over the entire land of Egypt” – why did He bring boils upon them? It is because they tasked Israel to heat hot water for them and to cool cold water for them;7The Israelites prepared water for them to bathe. therefore they were afflicted with boils so they would be unable to touch their bodies. Rabbi Yehoshua ben Levi said: A great miracle was performed with the boils, as when a person shoots an arrow upward it does not travel one hundred cubits, and Moses threw a handful of the soot of a furnace, which lacks substance, and Moses threw it heavenward and it reached the Throne of Glory.
Another miracle was performed with the boils, that what Moses’s hand held was two handfuls. Another miracle was performed with the boils: When a person scatters a kav of dust, it scatters only four cubits, but Moses took a handful8A handful is considerably less than a kav. and scattered it throughout the land of Egypt.
