Judges 9:4-5

9:4 They paid him seventy silver shekels out of the temple of Baal-Berith. Abimelech then used the silver to hire some lawless, dangerous men as his followers. 9:5 He went to his father’s home in Ophrah and murdered his half-brothers, the seventy legitimate sons of Jerub-Baal, on one stone. Only Jotham, Jerub-Baal’s youngest son, escaped, because he hid.
