Judges 9:19-20, 57

if you then have acted in good faith and integrity with Jerubbaal and with his house this day, then rejoice in Abimelech, and let him also rejoice in you. But if not, let fire come out from Abimelech and devour the leaders of Shechem and Beth-millo; and let fire come out from the leaders of Shechem and from Beth-millo and devour Abimelech.”

And God also made all the evil of the men of Shechem return on their heads, and upon them came the curse of Jotham the son of Jerubbaal.
