Judges 3:24 DBY

²³  Then Ehud went out into the vestibule, and closed the doors of the roof chamber upon him, and locked them.

²⁴  When he had gone, the servants came; and when they saw that the doors of the roof chamber were locked, they thought, 'He is only relieving himself in the closet of the cool chamber.'

²⁵  And they waited till they were utterly at a loss; but when he still did not open the doors of the roof chamber, they took the key and opened them; and there lay their lord dead on the floor.

²⁶  Ehud escaped while they delayed, and passed beyond the sculptured stones, and escaped to Se-i'rah.
