Judges 6:26-27

26and 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.” 27Then Gideon took ten men of his servants and did as the Lord had spoken to him; and because he was too afraid of his father’s household and the men of the city to do it by day, he did it by night.
