Judges 6:25; Judges 6:26

25 Now on the same night the LORD said to him, "Take your father's bull and a second bull seven years old, and pull down the altar of Baal which belongs to your father, and cut down the Asherah that is beside it;

26 and build an altar to the LORD your God on the top of this stronghold in an orderly manner, and take a second bull and offer a burnt offering with the wood of the Asherah which you shall cut down."
