Gideon obeyed at night

25And it happened that night that Yahweh said to him, “Take your father’s bull and the second bull, seven years old, and tear down the altar of Baal that belongs to your father, and cut down the Asherah that is upon it.”

26Then build an altar to Yahweh your God on the top of this stronghold, in orderly arrangement, and take the second bull and offer it up as a burnt offering with the wood of the Asherah that you cut down.

27So Gideon took ten men from among his servants and did as Yahweh had spoken to him. But because he feared his father's household and the men of the city too much to do it by day, he did it at night.
