Charles Ellicott Commentary Judges 9:46

"And when all the men of the tower of Shechem heard thereof, they entered into the stronghold of the house of Elberith." — Judges 9:46 (ASV)

The men of the tower of Shechem. —Evidently the garrison of the house of Millo (Judges 9:6).

Entered into a hold. —The word for “hold” occurs in 1 Samuel 13:6 (“high place”). The Septuagint renders it “a fortress” (ochuroma); Luther, “Festung.” In the Ethiopic Version of Mark 16:15, a similar word is used for “upper room.” The Vulgate has, “They entered the shrine of their god Berith, where they had made their league with him, and from this the place had received its name, and it was strongly fortified.”

Of the house of the god Berith. —Similarly, Arcesilas burned the Cyrenaeans in a tower (Herod. iv. 164), and in 1 Maccabees 5:43 the defeated enemy flee for refuge to the temple of Ashtaroth in Karnaim, which Judas takes and burns.
