Judges 9:1-2, 5-6

Abimelek son of Jerub-Baal went to his mother’s brothers in Shechem and said to them and to all his mother’s clan, “Ask all the citizens of Shechem, ‘Which is better for you: to have all seventy of Jerub-Baal’s sons rule over you, or just one man?’ Remember, I am your flesh and blood.”

He went to his father’s home in Ophrah and on one stone murdered his seventy brothers, the sons of Jerub-Baal. But Jotham, the youngest son of Jerub-Baal, escaped by hiding. Then all the citizens of Shechem and Beth Millo gathered beside the great tree at the pillar in Shechem to crown Abimelek king.
