The sixth plague, the plague of boils, was produced by Moses and Aaron together in a miraculous way. Each took a handful of ashes of the furnace, then Moses held the contents of the two heaps in the hollow of one of his hands, and sprinkled the ashes tip toward the heaven, and it flew so high that it reached the Divine throne. Returning earthward, it scattered over the whole land of Egypt, a space equal to four hundred square parasangs. The small dust of the ashes produced leprosy upon the skin of the Egyptians, and blains of a peculiar kind, soft within and dry on top.
