Thematic Bible: A range of low mountains

And Joshua saith unto them, 'If thou art a numerous people, go up for thee to the forest, then thou hast prepared for thee there, in the land of the Perizzite, and of the Rephaim, when mount Ephraim hath been narrow for thee.' And the sons of Joseph say, 'The hill is not found to us, and a chariot of iron is with every Canaanite who is dwelling in the land of the valley -- to him who is in Beth-Shean and its towns, and to him who is in the valley of Jezreel.' And Joshua speaketh unto the house of Joseph, to Ephraim and to Manasseh, saying, 'Thou art a numerous people, and hast great power; thou hast not one lot only, read more.
because the mountain is thine; because it is a forest -- thou hast prepared it, and its outgoings have been thine; because thou dost dispossess the Canaanite, though it hath chariots of iron -- though it is strong.'
