Judges 1:27

1:27 The men of Manasseh did not conquer Beth Shan, Taanach, or their surrounding towns. Nor did they conquer the people living in Dor, Ibleam, Megiddo or their surrounding towns. The Canaanites managed to remain in those areas.

Judges 11:26

11:26 Israel has been living in Heshbon and its nearby towns, in Aroer and its nearby towns, and in all the cities along the Arnon for three hundred years! Why did you not reclaim them during that time?
