At this time, the Hebrews were slaves, and had been for two hundred and fifteen years. A little while before, an order had been made by the Egyptians that all the male children of the Hebrews should be killed. One, contrary to this order, was saved in an ark made of bullrushes daubed with slime. This child was found by the daughter of Pharaoh, and was adopted, it seems, as her own, and, may be, was. He grew to be a man, sided with the Hebrews, killed an Egyptian that was smiting a slave, hid the body in the sand, and fled from Egypt to the land of Midian, became acquainted with a priest who had seven daughters, took the side of the daughters against the ill-mannered shepherds of that country, and married Zipporah, one of the girls, and became a shepherd for her father. Afterward, while tending his flock, the Lord appeared to him in a burning bush, and commanded him to go to the king of Egypt and demand from him the liberation of the Hebrews. In order to convince him that the something burning in the bush was actually God, the rod in his hand was changed into a serpent, which, upon being caught by the tail, became again a rod. Moses was also told to put his hand in his bosom, and when he took it out it was as leprous as snow. Quite a number of strange things were performed, and others promised. Moses then agreed to go back to Egypt provided his brother could go with him. Whereupon the Lord appeared to Aaron, and directed him to meet Moses in the wilderness. They met at the mount of God, went to Egypt, gathered together all the elders of the children of Israel, spake all the words which God had spoken unto Moses, and did all the signs in the sight of the people. The Israelites believed, bowed their heads and worshiped; and Moses and Aaron went in and told their message to Pharaoh the king. XXII. THE PLAGUES.
