Judges 3:16-23

16And Ehud made for himself a sword with two edges, a cubit in length, and he bound it on his right thigh under his clothes.

17And he presented the tribute to Eglon king of Moab. Now Eglon was a very fat man.

18And when Ehud had finished presenting the tribute, he sent away the people who carried the tribute.

19But he himself turned back at the idols near Gilgal and said, "I have a secret message for you, O king." And he commanded, "Silence." And all his attendants went out from his presence.

20And Ehud came to him as he was sitting alone in his cool roof chamber. And Ehud said, "I have a message from God for you." And he arose from his seat.

21And Ehud reached with his left hand, took the sword from his right thigh, and thrust it into his belly.

22And the hilt also went in after the blade, and the fat closed over the blade, for he did not pull the sword out of his belly; and the dung came out.

23Then Ehud went out into the porch and closed the doors of the roof chamber behind him and locked them.
