Judges 3:23-25

23Then Ehud went forth into the porch, and shut the doors of the parlour upon him, and locked them.

24Now when he was gone out, his servants came; and they saw, and, behold, the doors of the parlour were locked; and they said, Surely he covereth his feet in his summer chamber.

25And they tarried till they were ashamed: and, behold, he opened not the doors of the parlour; therefore they took the key, and opened them: and, behold, their lord was fallen down dead on the earth.
