'Mountains' in the Bible

Only unto the land of the children of Ammon thou camest not, nor unto any place of the river Jabbok, nor unto the cities in the mountains, nor unto whatsoever the LORD our God forbad us.

a land without scarcity. You'll eat food in it and lack nothing. It's a land where its rocks are iron and you can dig copper from its mountains."

But the land you are entering to possess is a land of mountains and valleys, watered by rain from the sky.

Aren’t these mountains across the Jordan, beyond the western road in the land of the Canaanites, who live in the Arabah, opposite Gilgal, near the oaks of Moreh?

Ye shall utterly destroy all the places, wherein the nations which ye shall possess served their gods, upon the high mountains, and upon the hills, and under every green tree:

For a fire is kindled in mine anger, and shall burn unto the lowest hell, and shall consume the earth with her increase, and set on fire the foundations of the mountains.

And for the chief things of the ancient mountains, and for the precious things of the lasting hills,

They summon people [to the] mountains; there they sacrifice the sacrifices of righteousness, because the affluence of [the] seas they suck [out], and {the most hidden treasures of the sand}."
