Judges 3:16-21
3:16 Ehud made himself a sword – it had two edges and was eighteen inches long.
He strapped it under his coat on his right thigh.
3:17 He brought the tribute payment to King Eglon of Moab. (Now Eglon was a very fat man.)
3:18 After Ehud brought the tribute payment, he dismissed the people who had carried it.
3:19 But he went back once he reached the carved images at Gilgal. He said to Eglon, “I have a secret message for you, O king.” Eglon said, “Be quiet!” All his attendants left.
3:20 When Ehud approached him, he was sitting in his well-ventilated upper room all by himself. Ehud said, “I have a message from God for you.” When Eglon rose up from his seat,
3:21 Ehud reached with his left hand, pulled the sword from his right thigh, and drove it into Eglon’s belly.
