Shofetim 3:22-24

Orthodox Jewish Bible

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.

²⁴ When he was gone out, his avadim came; and when they saw that, hinei, the daletot of the aliyyah were locked, they said, Surely he covereth his feet [i.e. relieves himself] in the chedar hamekerah (inner cool room).
