Judges 3:21-25

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

And 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.

Then Ehud went forth through the porch, and shut the doors of the parlour upon him, and locked them.

When he was gone out, his servants came; and when they saw that, behold, the doors of the parlour were locked, they said, Surely he covereth his feet in his summer chamber.

And they tarried till they were ashamed: and, behold, he opened not the doors of the parlour; therefore they took a key, and opened them: and, behold, their lord was fallen down dead on the earth.
