Verse 50: Then went Abimelech to Thebez, and encamped against Thebez, and took it.
[To Thebez] The city is in the tribe of Manasseh, as Adrichomius testifies (Menochius). It was not far from the city of Shechem, and apparently the other colony of the same city (Bonfrerius).
Thebez; another town near to Shechem; and, as it seems, within its territory.
[He besieged] In the Hebrew it is added, and he took it. He subjoins that the city was previously taken, otherwise the citizens would not have fled to the tower, neither would Abimelech have been able to approach (Bonfrerius).
Verse 51: But there was a strong tower within the city, and thither fled all the men and women, and all they of the city, and shut it to them, and gat them up to the top of the tower.
All the men and women; all that were not slain in the taking of the town; or they all forsook the town, and retired to their strong hold.
[With the entrance shut up, וַֽיִּסְגְּר֖וּ בַּעֲדָ֑ם] And they shut upon themselves, understanding, the stronghold, or the gate of the stronghold. Upon themselves, that is, after they entered (Vatablus).
[Upon the roof of the tower] For the roofs of the Jews were flat for walking, sunning oneself, conversing, etc. (Bonfrerius).
The top of the tower was flat and plain, after their manner of building.
Verse 52: And Abimelech came unto the tower, and fought against it, and went hard unto the door of the tower to burn it with fire.
