Joshua 14:12

14:12 Now, assign me this hill country which the Lord promised me at that time! No doubt you heard at that time that the Anakites live there in large, fortified cities. But, assuming the Lord is with me, I will conquer them, as the Lord promised.”

Joshua 17:15-16

17:15 Joshua replied to them, “Since you have so many people, go up into the forest and clear out a place to live in the land of the Perizzites and Rephaites, for the hill country of Ephraim is too small for you.” 17:16 The descendants of Joseph said, “The whole hill country is inadequate for us, and the Canaanites living down in the valley in Beth Shean and its surrounding towns and in the Valley of Jezreel have chariots with iron-rimmed wheels.”

Joshua 18:16

18:16 The border then descended to the edge of the hill country near the Valley of Ben Hinnom located in the Valley of the Rephaites to the north. It descended through the Valley of Hinnom to the slope of the Jebusites to the south and then down to En Rogel.
