Judges 3:18-20

18And it came to pass when he had ended offering the gift, he sent away the people that had borne the gift.

19But he turned from the graven images that were by Gilgal, and said, I have a secret word unto thee, O king. And he said, Be silent! And all that stood by him went out from him.

20And Ehud came to him; now he was sitting in the cool upper-chamber, which was for him alone. And Ehud said, I have a word from 1God unto thee. And he arose from the seat.
