Judges 3:19-20

19But when Ehud reached the stone idols at Gilgal, he turned round to go back to the king. He said to King Eglon, ‘I have a secret message for you, sir!’ So the king said, ‘Leave us alone.’ All his servants went out.

20The king was now sitting alone in his cool room on the roof of the palace. Ehud went near to the king and he said, ‘I have a message from God for you.’ The king started to get up from his chair.
