Judges 3:15-16

3:15 When the Israelites cried out for help to the Lord, he raised up a deliverer for them. His name was Ehud son of Gera the Benjaminite, a left-handed man. The Israelites sent him to King Eglon of Moab with their tribute payment. 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.
