When all the men of the tower of Shechem heard of it, they entered into the stronghold of the house of Elberith.
"The stronghold"  (Judges 9:46).  "This stronghold appears to have been a vault-like structure beneath the temple of Baal-berith ...  It is ironic that the words of Jotham's fable and the threat of fire coming out of the bramble (Abimelech) and devouring the Shechemites should have had such a literal fulfillment as that which is depicted here."[23]
