Judges 3:23-25

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

24Now when he was gone out, his servants came; and they saw, and, behold, the doors of the upper room were locked; and they said, Surely he is covering his feet in the upper chamber. 25And they tarried till they were ashamed; and, behold, he opened not the doors of the upper room: therefore they took the key, and opened them; and, behold, their lord was fallen down dead on the earth.
