Ehud made himself a double-edged sword 18 inches long. He strapped it to his right thigh under his clothes

He went to his father’s house in Ophrah and killed his 70 brothers, the sons of Jerubbaal, on top of a large stone. But Jotham, the youngest son of Jerubbaal, survived, because he hid himself.
