Judges 3:20

16Ehud made himself a sword which had two edges, a cubit in length; and he wore it under his clothing on his right thigh.

17He offered the tribute to Eglon king of Moab. Now Eglon was a very fat man.

18When Ehud had finished offering the tribute, he sent away the people who carried the tribute.

19But he himself turned back from the stone idols that were by Gilgal, and said, “I have a secret message for you, O king.” The king said, “Keep silence!” All who stood by him left him.

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.”
