46 Then all the townsmen of the tower of Shechem, hearing of it, went into the inner room of the house of El-berith. 47 And word was given to Abimelech that all the men of the tower of Shechem were there together. 48 Then Abimelech went up to Mount Zalmon, with all his people; and Abimelech took an axe in his hand and, cutting down branches of trees, took them and put them on his back. And he said to the people who were with him, Be quick and do as you have seen me do. 49 So all the people got branches, every man cutting down a branch, and they went with Abimelech at their head and, massing the branches against the inner room, put fire to the room over them; so all those who were in the tower of Shechem, about a thousand men and women, were burned to death with it.

Commentary on Judges 9:30-49

(Read Judges 9:30-49)

Abimelech intended to punish the Schechemites for slighting him now, but God punished them for their serving him formerly in the murder of Gideon's sons. When God uses men as instruments in his hand to do his work, he means one thing, and they another. That, which they hoped would have been for their welfare, proved a snare and a trap, as those will certainly find, who run to idols for shelter; such will prove a refuge of lies.
