Albert Barnes Commentary Judges 6:25

"And it came to pass the same night, that Jehovah said unto him, Take thy father`s bullock, even the second bullock seven years old, and throw down the altar of Baal that thy father hath, and cut down the Asherah that is by it;" — Judges 6:25 (ASV)

Even - Rather, as in the margin, and. Two bullocks are spoken of. The labor of both would be required for pulling down and removing the altar of Baal, and for bringing the materials for building the altar of Yahweh.

The grove by it - Rather, “the idol upon it,” the Asherah, the wooden image of Astarte (Judges 3:7).
