Albert Barnes Commentary Judges 6:27

"Then Gideon took ten men of his servants, and did as Jehovah had spoken unto him: and it came to pass, because he feared his father`s household and the men of the city, so that he could not do it by day, that he did it by night." — Judges 6:27 (ASV)

The mention of the “men of the city” alongside Gideon’s “father’s household” suggests the probability of their being a remnant of the Canaanite population, and the special patrons of Baal-worship.
