Judg 6:25-26

25That night the Lord said to him, “Take your father's bull, the second bull seven years old, and pull down the altar of Baal that belongs to your father, and cut down the sacred pole that is beside it;26and build an altar to the Lord your God on the top of the stronghold here, in proper order; then take the second bull, and offer it as a burnt offering with the wood of the sacred pole that you shall cut down.”
