Judges 6:25-26

25And it came to pass the same night, that the LORD said unto him, Take thy father’s bullock, even the second bullock of seven years old, and throw down the altar of Baal that thy father hath, and cut down the Asherah that is by it:

26and build an altar unto the LORD thy God upon the top of this strong hold, in the orderly manner, and take the second bullock, and offer a burnt offering with the wood of the Asherah which thou shalt cut down.
