Abimelech (Judges)
Abimelech, son of Gideon (also called Jerubbaal), is a figure in the Book of Judges (chapter 9). He is notable for attempting to establish himself as king over Israel after the death of his father, who had refused kingship when offered it.
Abimelech conspired with his mother's relatives in Shechem to kill all but one of his seventy half-brothers in order to secure his position. Only Jotham, the youngest son of Gideon, escaped the massacre. Jotham then delivered a parable from Mount Gerizim about the trees choosing a king, prophesying Abimelech's downfall.
Abimelech was indeed made king by the people of Shechem and Beth Millo. However, his reign was short and violent. Internal strife arose between Abimelech and the people of Shechem, leading to rebellion. Gaal led the Shechemites in opposition to Abimelech.
Abimelech eventually subdued the rebellion and destroyed Shechem. He then besieged the tower of Thebez. During the siege, a woman dropped a millstone from the city wall, crushing Abimelech's skull. Mortally wounded, he ordered his armor-bearer to kill him so that it would not be said that he was killed by a woman. His ambition ultimately led to his demise, fulfilling Jotham's curse. The narrative of Abimelech serves as a cautionary tale about the dangers of ambition and the rejection of God's chosen leadership.
