Judges 9:19-20, 57

So then, if you have been honest and sincere to Gideon and his family today, be happy with Abimelech as your king. And may he be happy with you! But if not, may fire come out of Abimelech and completely burn you leaders of Shechem and Beth Millo! Also may fire come out of the leaders of Shechem and Beth Millo and burn up Abimelech!”

God also punished the men of Shechem for the evil they had done. So the curse spoken by Jotham, the youngest son of Gideon, came true.
