By these phrases, the author means the Israelites who lived in the territory north of the Valley of Jezreel and west of the Jordan River. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [who lived in the territory north of the Valley of Jezreel and west of the Jordan River]
