Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

When the inhabitants of the castle of Shechem ("lords of the tower of Shechem" = "all the house of Millo," Jdg 9:6) heard of the fate of the town of Shechem, they betook themselves to the hold of the house (temple) of the covenant god (Baal-berith), evidently not for the purpose of defending themselves there, but to seek safety at the sanctuary of their god from fear of the vengeance of Abimelech, towards whom they also had probably acted treacherously. The meaning of the word צריח, which answers to an Arabic word signifying arx, palatium, omnis structura elatior, cannot be exactly determined, as it only occurs again in Sa1 13:6 in connection with caves and clefts of the rock. According to v. 49, it had a roof which could be set on fire. The meaning "tower" is only a conjecture founded upon the context, and does not suit, as צריח is distinguished from מגדּל. Jdg 9:47-49 As soon as this was announced to Abimelech, he went with all his men to Mount Zalmon, took hatchets in his hand, cut down branches from the trees, and laid them upon his shoulders, and commanded his people to do the same. These branches they laid upon the hold, and set the hold on fire over them (the inhabitants of the tower who had taken refuge there), so that all the people of the tower of Shechem (about one thousand persons) perished, both men and women. Mount Zalmon, which is mentioned again in Psa 68:15, was a dark, thickly-wooded mountain near Shechem, - a kind of "Black Forest," as Luther has rendered the name. The plural kardumoth, "axes," may be explained on the ground that Abimelech took axes not only for himself but for his people also. מה in a relative sense, as in Num 23:3 (see Ewald, 331, b.).
