Judges 3:19-23

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.

The hilt of the sword also went in after the blade, and the fat closed over the blade because he did not pull the sword out of his belly; and the refuse came out.

Then Ehud went out into the vestibule, and shut the doors of the roof chamber behind him, and locked them.
