Judges 3:17-21

Then he presented the tribute to Eglon king of Moab. Now Eglon was a very fat man.

And it came about, when he had finished presenting the tribute, that Ehud sent away the people who had carried the tribute.

But he himself turned back from the idols which were at Gilgal, and said, “I have a secret message for you, O king.” And the king said, “Silence!” And all who were attending him left him.

Then Ehud came to him while he was sitting in his cool roof chamber alone. And Ehud said, “I have a message from God for you.” And he got up from his seat.

Then Ehud reached out with his left hand and took the sword from his right thigh, and thrust it into his belly.
