Judges 3:19-20

19But he himself turned back from the stone images that were at Gilgal, and said, “I have a secret message for you, O king.” He said, “Keep silence!” And all who attended him went out from him.

20So Ehud came to him (now he was sitting upstairs in his cool private chamber). Then Ehud said, “I have a message from God for you.” So he arose from his seat.
