Judges 3:23-25

23Ehud went out of the room and he locked the doors. Then he escaped from the palace.

24The king's servants came up to the room on the roof. They saw that the doors were locked. They thought that the king was using the toilet inside.

25They waited for a long time and they started to worry. But the king still did not open the doors of his room. So they took the key and they opened the doors. Then they saw their master, the king! He was lying on the floor and he was dead.
