Most writers, however, agree in stating that once a disease, which horribly disfigured the body, broke out over Egypt; that king Bocchoris, seeking a remedy, consulted the oracle of Hammon, and was bidden to cleanse his realm, and to convey into some foreign land this race detested by the gods. The people, who had been collected after diligent search, finding themselves left in a desert, sat for the most part in a stupor of grief, till one of the exiles, Moses by name, warned them not to look for any relief from God or man, forsaken as they were of both, but to trust to themselves, taking for their heaven-sent leader that man who should first help them to be quit of their present misery. They agreed, and in utter ignorance began to advance at random. Nothing, however, distressed them so much as the scarcity of water, and they had sunk ready to perish in all directions over the plain, when a herd of wild asses was seen to retire from their pasture to a rock shaded by trees. Moses followed them, and, guided by the appearance of a grassy spot, discovered an abundant spring of water. This furnished relief. After a continuous journey for six days, on the seventh they possessed themselves of a country, from which they expelled the inhabitants, and in which they founded a city and a temple.
