25 That night this happened. God said to him, "Take your father's best seven-year-old bull, the prime one. Tear down your father's Baal altar and chop down the Asherah fertility pole beside it. 26 Then build an altar to God, your God, on the top of this hill. Take the prime bull and present it as a Whole-Burnt-Offering, using firewood from the Asherah pole that you cut down." 27 Gideon selected ten men from his servants and did exactly what God had told him. But because of his family and the people in the neighborhood, he was afraid to do it openly, so he did it that night. 28 Early in the morning, the people in town were shocked to find Baal's altar torn down, the Asherah pole beside it chopped down, and the prime bull burning away on the altar that had been built. 29 They kept asking, "Who did this?" Questions and more questions, and then the answer: "Gideon son of Joash did it." 30 The men of the town demanded of Joash: "Bring out your son! He must die! Why, he tore down the Baal altar and chopped down the Asherah tree!"

Commentary on Judges 6:25-32

(Read Judges 6:25-32)

See the power of God's grace, that he could raise up a reformer; and the kindness of his grace, that he would raise up a deliverer, out of the family of a leader in idolatry. Gideon must not think it enough not to worship at that altar; he must throw it down, and offer sacrifice on another. It was needful he should make peace with God, before he made war on Midian. Till sin be pardoned through the great Sacrifice, no good is to be expected. God, who has all hearts in his hands, influenced Joash to appear for his son against the advocates for Baal, though he had joined formerly in the worship of Baal. Let us do our duty, and trust God with our safety. Here is a challenge to Baal, to do either good or evil; the result convinced his worshippers of their folly, in praying to one to help them that could not avenge himself.
