34 So Abimelech and the people with him got up by night, in four bands, to make a surprise attack on Shechem. 35 And Gaal, the son of Ebed, went out, and took his place at the doorway into the town; then Abimelech and his people got up from the place where they had been waiting. 36 And when Gaal saw the people, he said to Zebul, See! people are coming down from the tops of the mountains. And Zebul said to him, You see the shade of the mountains like men. 37 And Gaal said again, See! people are coming down from the middle of the land, and one band is coming by way of the oak-tree of the Seers. 38 Then Zebul said to him, Now where is your loud talk when you said, Who is Abimelech that we are to be his servants? Is this not the people whom you were rating so low? Go out now, and make war on them. 39 So Gaal went out at the head of the townsmen of Shechem and made war on Abimelech. 40 And Abimelech went after him and he went in flight before him; and a great number were falling by the sword all the way up to the town. 41 Then Abimelech went back to Arumah; and Zebul sent Gaal and his brothers away and would not let them go on living in Shechem. 42 Now the day after, the people went out into the fields; and news of it came to Abimelech. 43 And he took his people, separating them into three bands, and was waiting secretly in the field; and when he saw the people coming out of the town, he went up and made an attack on them. 44 And Abimelech with his band made a rush, and took up their position at the doorway into the town; and the other two bands made a rush on all those who were in the fields, and overcame them. 45 And all that day Abimelech was fighting against the town; and he took it, and put to death the people who were in it, and had the town pulled down and covered with salt.

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.
