Judges 3:22

²⁰And Ehud went in to him; and he sat in his own upper summer chamber quite alone; and Ehud said, I have a message from God to thee, O king: and Eglon rose up from his throne near him.

²¹And it came to pass as he arose, that Ehud stretched forth his left hand, and took the dagger off his right thigh, and plunged it into his belly;

— Judges 3:22 —

²³And Ehud went out to the porch, and passed out by the appointed guards, and shut the doors of the chamber upon him, and locked them.

²⁴And he went out: and Eglon’s servants came, and saw, and behold, the doors of the upper chamber were locked; and they said, Does he not uncover his feet in the summer chamber?
