31 Secretly he sent messengers to Abimelech with the message, "Gaal son of Ebed and his relatives have come to Shechem and are stirring up trouble against you.

Matthew Henry's Commentary on Judges 9:31

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.
