Yes, the Bible expressly mentions the curse in Judges chapter 9 verse 20.  Jo t h a m, Gideon's lone youngest son that survived the slaughter of being killed on the one rock; he stood up like a man and gave them a lecture about the trees and the vines. Jotham stated in  verse 9:20,  "But if not, let  fire come out from Abimelech and devour the men of Shechem  and the house of Millo; and let fire come out from the men of Shechem, and from the house of Millo and devour Abimelech ." So Abimelech was slain by a woman throwing the stone from the tower before it burned and then he was also burned  when the tower fell from the burning . And in Judges chapter 9 verse 52 -57, shows that the fire that appears to be started by man; apparently the curse was fulfilled and that the fire was really from from Jehovah. So Jo t h a m told the curse and it was fulfilled 3 years later. He was killed by a stone or rock , the same object that Gideon's sons were slain by.
