Judges 3:20 KJV

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.

21And Ehud put forth his left hand, and took the dagger from his right thigh, and thrust it into his belly:

22And the haft also went in after the blade; and the fat closed upon the blade, so that he could not draw the dagger out of his belly; and the dirt came out.
