Judges 3:23-25

23And Ehud went out into the portico, and shut the doors of the upper-chamber upon him, and bolted them.

24And when he was gone out, the servants of the [king] came and saw, and behold, the doors of the upper-chamber were bolted. And they said, Surely he is covering his feet in the summer chamber.

25And they waited till they were ashamed; and behold, he opened not the doors of the upper-chamber, and they took the key, and opened [them], and behold, their lord lay dead on the earth.
