Judges 3:23-25

23Then Ehud went forth through the porch, and shut the doors of the parlour upon him, and locked them. 24When he had gone out, his servants came; and when they saw that, behold, the doors of the parlour were locked, they said, Surely he covereth his feet in his summer chamber.1 25And they tarried till they were ashamed: and, behold, he opened not the doors of the parlour; therefore they took a key, and opened them : and, behold, their lord lay dead on the earth.
