Ehud walked over to Eglon, who was sitting alone in a cool upstairs room. And Ehud said, "I have a message from God for you!" As King Eglon rose from his seat, Ehud reached with his left hand, pulled out the dagger strapped to his right thigh, and plunged it into the king's belly. The dagger went so deep that the handle disappeared beneath the king's fat. So Ehud did not pull out the dagger, and the king's bowels emptied. Then Ehud closed and locked the doors of the room and escaped down the latrine. After Ehud was gone, the king's servants returned and found the doors to the upstairs room locked. They thought he might be using the latrine in the room, so they waited. But when the king didn't come out after a long delay, they became concerned and got a key. And when they opened the doors, they found their master dead on the floor. While the servants were waiting, Ehud escaped, passing the stone idols on his way to Seirah.
