Judges 3:17-19

And he offered the tribute unto Eglon king of Moab: now Eglon was a very fat man. And when he had made an end of offering the tribute, he sent away the people that bare the tribute. But he himself turned back from the quarries that were by Gilgal, and said, I have a secret errand unto thee, O king. And he said, Keep silence. And all that stood by him went out from him.
