Now the king might ask, what authority have you to tell me to let the people of Israel go? So God had told him to take a staff with him and cast it on the floor, and it should become a serpent in the sight of Pharaoh. Pharaoh was greatly frightened when he saw the serpent on the floor, but he refused to hear God, and let the peo- ple go, and did not until repeated judgments had been sent upon him. You have read how God sent frogs over all the land, so that they filled their houses, and the people would find them in the tray where they mixed their bread. God sent lice upon them, to cover man and beast. He turned the rivers and streams to blood, so that the people could not get any pure water. These were some of the terrible afflictions which the Lord sent upon the people of Egypt, to make them willing to let his people go. At last, when God had tried everything else to no purpose, he determined to make Pharaoh willing, by de- stroying the first-born in every family. We learn of this in the next lesson. God wanted to lead his people back into Canaan, and separate them from other nations, to make of them a great nation for himself. This is why he allowed them to suffer so in Egypt, that they might not want to stay there.
