Thus it was that Aaron, the elder brother, as also Moses and Miriam, had grown up in an atmosphere of greater moral and religious purity. Of Moses the historical records relate that after his birth his mother kept him concealed during three months, to evade the royal command, and protect him from death in the waters of the Nile. There is no doubt that the youthful Moses was well acquainted with Pharaoh's court at Memphis or Tanis (Zoan). Gifted with an active intellect, he had an opportunity of acquiring the knowledge that was to be learnt in Egypt, and by his personal and intellectual qualities he won the affections of all hearts. But even more than by these qualities, he was distinguished by his gentleness and modesty. "Moses was the meekest of men," is the only praise which the historical records have bestowed upon him. He is not praised for heroism or warlike deeds, but for unselfishness and self-abnegation. Influenced by the ancient teaching, that the God of Abraham loved righteousness, he must have been repelled by the baseless idolatry of animal worship and by the social and moral wrongs which then were rife. Shameless vice, the bondage of a whole people under kings and priests, the inequality of castes, the treatment of human beings as though they were beasts or inferior to beasts, the spirit of slavery,--all these evils he recognised in their full destructive force, and he perceived that the prevailing debasement had defiled his brethren. Moses was the open antagonist of injustice. It grieved him sorely that Israel's sons were subjected to slavery, and were daily exposed to ill-treatment by the lowest of the Egyptians. One day when he saw an Egyptian unjustly beating a Hebrew, his passion overcame his self-control, and he punished the offender. Fearing discovery, he fled from Egypt into the desert, and halted at an oasis in the neighbourhood of Mount Sinai, where the Kenites, an offshoot of the tribe of Midianites, were dwelling. Here, as in Egypt, he witnessed oppression and wrong-doing, and here also he opposed it with zeal. He gave his aid to feeble shepherdesses. By such action he came into contact with their grateful father, the priest or elder of the tribe of the Midianites, and he married Zipporah, the daughter of that priest. His employment in Midian was that of a shepherd. He selected fertile grazing plots for the herds of Reuel, his father-in-law, between the Red Sea and the mountain lands. In this solitude the prophetic spirit came upon him.
