Again the Israelites cried out to the Lord, and he gave them a deliverer—Ehud, a left-handed man, the son of Gera the Benjamite. The Israelites sent him with tribute to Eglon king of Moab. Now Ehud had made a double-edged sword about a cubit3:16 That is, about 18 inches or about 45 centimeters long, which he strapped to his right thigh under his clothing. He presented the tribute to Eglon king of Moab, who was a very fat man. After Ehud had presented the tribute, he sent on their way those who had carried it. But on reaching the stone images near Gilgal he himself went back to Eglon and said, “Your Majesty, I have a secret message for you.”
The king said to his attendants, “Leave us!” And they all left.
Ehud then approached him while he was sitting alone in the upper room of his palace3:20 The meaning of the Hebrew for this word is uncertain; also in verse 24. and said, “I have a message from God for you.” As the king rose from his seat, Ehud reached with his left hand, drew the sword from his right thigh and plunged it into the king’s belly.
