Judges 3:18 KJV

16But Ehud made him a dagger which had two edges, of a cubit length; and he did gird it under his raiment upon his right thigh.

17And he brought the present unto Eglon king of Moab: and Eglon was a very fat man.

18And when he had made an end to offer the present, he sent away the people that bare the present.

19But he himself turned again from the quarries that were by Gilgal, and said, I have a secret errand unto thee, O king: who said, Keep silence. And all that stood by him went out from him.

20And Ehud came unto him; and he was sitting in a summer parlour, which he had for himself alone. And Ehud said, I have a message from God unto thee. And he arose out of his seat.
