Judges 3:22

20Ehud came to him; and he was sitting by himself alone in the cool upper room. Ehud said, “I have a message from God to you.” He arose out of his seat.

21Ehud put out his left hand, and took the sword from his right thigh, and thrust it into his body.

22The handle also went in after the blade; and the fat closed on the blade, for he didn’t draw the sword out of his body; and it came out behind.

23Then Ehud went out onto the porch, and shut the doors of the upper room on him, and locked them.

24After he had gone, his servants came and saw that the doors of the upper room were locked. They said, “Surely he is covering his feet in the upper room.”
