What does Judges 3:23 mean?
In modern English slang, someone who is emotionless, capable, and ruthless in what they do is referred to as "an assassin." In this notably graphic episode from Scripture, Ehud fits such a description in every possible way. He has just killed the king of Moab, in the king's own palace, using a hidden, handmade stabbing weapon (Judges 3:16–21). Ehud's strike buried the entire forearm-length weapon into the king's stomach, resulting in a messy, graphic, and fatal injury (Judges 3:22).With level-headed calm, it seems, Ehud now walks out of the room, closing and locking the doors behind him. The king's attendants were ordered to leave; no one is there to know what has happened. Presumably, Ehud simply walks away from the palace before anyone even suspects the king, Eglon, is dead. This calm exit is all the more effective because the attendants assume their king wants to be left alone. They delay a long time before unlocking the doors to find his corpse (Judges 3:24–25).
Instead of starting off by leading Israel's armies into battle, this deliverer raised up by God (Judges 2:16) walked into the enemy king's palace and killed him outright. Ehud's bravery takes the form of both deception and bold action.
There is a battle still to come, however, and Ehud will be leading that charge (Judges 3:26–29).
