These tribes led a simple life in the land of Goshen. The elders (_Zekenim_) of the families, who acted as their chiefs, were consulted on all important occasions. They had no supreme chieftain, nor did they owe allegiance to the Egyptian kings; and thus they habitually enjoyed the freedom of a republic, in which each tribal section was enabled to preserve its independence without falling into subjection or serfdom. Although they did not become intermixed with the ancient Egyptians, who in fact had an aversion to shepherds--perhaps on account of the oppression they had in former ages endured from such shepherds (the Hyksos)--yet opportunities for contact and mutual communication could not be wanting. Some families of Israel had abandoned their pastoral pursuits, and devoted themselves to agriculture or industrial occupations, and were therefore brought into connection with the inhabitants of towns. It seems that the members of the tribe of Ephraim stood in closer social contact with the original inhabitants. This intercourse had a favourable influence upon the Israelites. The Egyptians had already gone through a history of a thousand years, and attained to a high degree of culture. Their kings, or Pharaohs, had already built populous cities, and erected colossal edifices, temples, pyramids and mausoleums. Their priests had acquired a certain degree of perfection in such arts and technical accomplishments as were suited to the requirements of the country, as for example, architecture and hydraulic constructions, the kindred science of geometry, the art of medicine, and the mystery of embalming for the perpetual preservation of the remains of the departed; also the artistic working of objects in gold, silver and precious stones, in order to satisfy the luxurious demands of the kings. They also knew the art of sculpture and the use of pigments. They studied chronology, together with astronomy, which was suggested by the periodical overflow of the Nile. The all-important art of writing had been invented and perfected by the Egyptian priests. They first used stones and metals to commemorate the renown of their monarchs; and they afterwards employed the fibre of the papyrus shrub, which was originally marked with clumsy figures and subsequently with ingeniously drawn symbols. Of these several attainments the Israelites seem to have acquired some notion. The members of the destitute tribe of Levi in particular, being unencumbered by pastoral service or by landed possessions, appear to have learnt from the Egyptian priests the art of writing. Owing to their superior knowledge, they were treated by the other tribes as the sacerdotal class, and hence they held, even in Egypt, the privileged distinction of their priestly position.
