What does Judges 3:27 mean?
Up until this point, Ehud's career as a deliverer and judge of Israel (Judges 2:16) involved working alone. After the Lord raised him up to save Israel from the Moabites, Ehud helped to deliver a tribute to the Moabite king before doubling back and killing the enemy ruler on his own (Judges 3:19–23).As crucial as it would be to kill the enemy's king, that act alone will not necessarily set Israel free. The people need to press their advantage while they still can. So, Ehud rallies the people of Israel to follow him into battle against the Moabites. He sounds a ram's horn trumpet as a signal to the fighting men of the region to join him. Perhaps they had already heard of his daring slaughter of the enemy king. Together, they follow Ehud out of the hill country and towards the Jordan River to attack the Moab army and keep them from regrouping in their home territory to launch reprisal attacks.
