Elated by the victory over Sisera, Israel sang a hymn of praise, the song of Deborah, and God, to reward them for their pious sentiments, pardoned the transgression of the people. (92) But they soon slipped back into the old ways, and the old troubles harassed them. Their backsliding was due to the witchcraft of a Midianite priest named Aud. He made the sun shine at midnight, and so convinced the Israelites that the idols of Midian were mightier than God, and God chastised them by delivering them into the hands of the Midianties. (93) They worshipped their own images reflected in the water, (94) and they were stricken with dire poverty. They could not bring so much as a meal offering, the offering of the poor. (95) On the eve of one Passover, Gideon uttered the complaint: "Where are all the wondrous works which God did for our fathers in this night, when he slew the first-born of the Egyptians, and Israel went forth from slavery with joyous hearts?" God appeared unto him, and said: "Thou who art courageous enough to champion Israel, thou art worthy that Israel should be saved for thy sake." (96) An angel appeared, and Gideon begged him for a sign, that he would achieve the deliverance of Israel. He excused his petition with the precedent of Moses, the first prophet, who likewise has asked for a sign. The angel bade him pour water on the rock, and then gave him the choice of how he would have the water transformed. Gideon desired to see one-half changed into blood, and one-half into fire. Thus it happened. The blood and the fire mingled with each other, yet the blood did not quench the fire, nor did the fire dry out the blood. Encouraged by this and other signs, (97) Gideon undertook to carry on the war against the Midianites with a band of three hundred God-fearing men, and he was successful. Of the enemy one hundred and twenty thousand corpses covered the field, and all the rest fled precipitately. (98) Gideon enjoyed the privilege of bringing salvation to Israel because he was a good son. His old father feared to thresh his grain on account of the Midianites, and Gideon once went out to him in the field and said: "Father, thou art too old to do this work; go thou home, and I shall finish thy task for thee. If the Midianites should surprise me out here, I can run away, which thou canst not do, on account of thy age." (99) The day on which Gideon gained his great victory was during the Passover, and the cake of barley bread that turned the camp of the enemy upside down, of which the Midianite dreamed, was a sign that God would espouse the cause of His people to reward them for bringing a cake of barley bread as an 'Omer offering.
