(30) The ruler of the city.--The word sar seems to imply that he was the military commandant.

Verses 30, 31. - And when Zebul, etc. Zebul, it appears, was governor of the city under Abimelech, and when the words of Gaal were reported to him, he privately sent off messengers to the king to tell him the state of affairs at Shechem, and urge him to come in person. Zebul meanwhile temporised, not being strong enough to resist Gaal openly. Privily. The word only occurs here. It probably means a little more than privily, - viz., with subtlety or deceit, - because he pretended all the while to be a friend of Gaal. Some make it a proper name, "In Rumah," taking it for the same place as Arumah (ver. 41)

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.And when Zebul the ruler of the city,.... Whom Abimelech had placed there under him: heard

the words of Gaal the son of Ebed, his anger was kindled; because he spoke slightly of him, and wished to have his place; perhaps before Zebul was inclined to be on the side of the Shechemites against Abimelech, or at least dissembled that he was; but now, being incensed at the words of Gaal, determined to take the side of Abimelech, and let him know how things were carrying on against him.
