The sixth plague of Egypt was Shkhin (sh'chin). The Shkhin was a kind of skin disease, usually translated as "boils". God commanded Moses and Aaron to each take two handfuls of soot from a furnace, which Moses scattered skyward in Pharaoh's presence. The soot induced festering Shkhin eruptions on Egyptian men and livestock. The Egyptian sorcerers were afflicted along with everyone else, and were unable to heal themselves, much less the rest of Egypt.
