The author assumes that his readers will know that the people of Thebez were Canaanites and that he can therefore use the phrase the men of Israel to mean the soldiers who were fighting with Abimelech against Thebez. (Apparently many Israelites were loyal to Abimelech, even though it was the Canaanites who lived in Shechem who first made him king on the basis that he had a Canaanite mother.) You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [the Israelites who had been supporting Abimelech]
