Judges 3:14-16

The Israelites were subject to Eglon king of Moab for eighteen years. 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 cubit long, which he strapped to his right thigh under his clothing.
