When the Jews had a written language, and that must have been long after their flight from Egypt, they wrote out their history and their laws. Tradition had filled the infancy of the nation with miracles and special interpositions in their behalf by Jehovah. Patriotism would not allow these wonders to grow small, and priestcraft never denied a miracle. There were traditions to the effect that God had spoken face to face with Moses; that he had given him the tables of the law, and had, in a thousand ways, made known his will; and whenever the priests wished to make new laws, or amend old ones, they pretended to have found something more that God said to Moses at Sinai. In this way obedience was more easily secured. Only a very few of the people could read, and, as a consequence, additions, interpolations and erasures had no fear of detection. In this way we account for the fact that Moses is made to speak of things that did not exist in his day, and were unknown for hundreds of years after his death. In the thirtieth chapter of Exodus, we are told that the people, when numbered, must give each one a half shekel after the shekel of the _sanctuary_. At that time no such money existed, and consequently the account could not, by any possibility, have been written until after there was a shekel of the sanctuary, and there was no such thing until long after the death of Moses. If we should read that Cæsar paid his troops in pounds, shillings and pence, we would certainly know that the account was not written by Cæsar, nor in his time, but we would know that it was written after the English had given these names to certain coins. So, we find, that when the Jews were upon the desert it was commanded that every mother should bring, as a sin offering, a couple of doves to the priests, and the priests were compelled to eat these doves in the most holy place. At the time this law appears to have been given, there were three million people, and only three priests, Aaron, Eleazer and Ithamar. Among three million people there would be, at least, three hundred births a day. Certainly we are not expected to believe that these three priests devoured six hundred pigeons every twenty-four hours.
