'Stone' in the Bible

and he goeth into the house of his father at Ophrah, and slayeth his brethren, sons of Jerubbaal, seventy men, on one stone; and Jotham, youngest son of Jerubbaal, is left, for he was hidden.

and ye have risen against the house of my father to-day, and slay his sons, seventy men, on one stone, and cause Abimelech son of his handmaid to reign over the masters of Shechem, because he is your brother --

among all this people are seven hundred chosen men, bound of their right hand, each of these slinging with a stone at the hair, and he doth not err.
