Judges 9:4-5

And they gave him threescore and ten pieces of silver out of the house of Baalberith, wherewith Abimelech hired vain and light persons, which followed him.

And he went unto his father's house at Ophrah, and slew his brethren the sons of Jerubbaal, being threescore and ten persons, upon one stone: notwithstanding yet Jotham the youngest son of Jerubbaal was left; for he hid himself.
