What does Judges 9:36 mean?
Zebul is Abimelech's officer over the city of Shechem (Judges 9:1–6; 30). And yet, apparently Zebul was cautious about openly expressing his loyalty to Abimelech. The same noblemen who appointed Abimelech no longer want him as their lord (Judges 9:22–25). Instead, they have embraced Gaal, who has openly bragged he would remove Abimelech from power if given the chance (Judges 9:26–29).Gaal and Zebul stand at the city's eastern gate at sunrise. Zebul has arranged for Abimelech to ambush Gaal and take the city by force (Judges 9:30–33). Gaal has no idea what's coming. As the rising sun hits his eyes, it creates deep shadows over the forested hills to the north and south. It is from these shadows that Abimelech and his four companies are charging the city.
Gaal points out movement to Zebul and says it looks like people are coming down the city from the nearby mountaintops. Zebul dismisses it as a trick of the eyes. He lies, telling Gaal it is only the shadows of the mountains. Zebul will reveal the truth, however, as soon as Abimelech's men are too close to be stopped (Judges 9:37–39).
