What is notable about the fact that the people of Israel follow Ehud?
Judges 3:27 (ESV)
27When he arrived, he sounded the trumpet in the hill country of Ephraim. Then the people of Israel went down with him from the hill country, and he was their leader.
Ehud had blown the trumpet in the hill country of Ephraim (Judges 3:26), but as the people are gathered, it is not the people of Ephraim in particular, but the people of Israel in general who follow Ehud.
27 When he arrived, he sounded the trumpet in the hill country of Ephraim. Then the people of Israel went down with him from the hill country, and he was their leader.
