The tribe of Benjamin produced many heroes, like Ehud and Saul, but it also showed great unfaithfulness to the covenant, unlike Judah (see Judges 20:18). Like Judah in its first battle (Judges 1:4–8), Benjamin faced strong people in a large city but chose to share the city with them. There is no mention of the Lord's presence (compare Judges 1:19, 22). The Jebusite city stayed under Canaanite control until David's time.
The phrase "to this day" highlights either ongoing historical situations (here and Judges 6:24) or the continuation of certain customs to a later time (1:26; 10:4; 15:19; 18:12).
