Shofetim 3:21-23

Orthodox Jewish Bible

²¹ And Ehud put forth his semol (left hand), and drew the cherev from his right thigh, and thrust it into his belly;

²² And even the hilt went in after the blade; and the chelev closed upon the blade, so that he could not draw the cherev out of his belly; it came out the back.

²³ Then Ehud went forth through the front hall, and shut the daletot of the aliyyah behind him, and locked them.
