'Hills' in the Bible

Surely, an illusion [comes] from [the] hills, [the] turmoil [on] the mountains. Surely, in Yahweh our God [is] the salvation of Israel.

I looked at the mountains, and behold, they were quaking, and all of the hills were jolted to and fro.

Your adulteries, and your neighings, the shameful behavior of your fornications on [the] hills in the countryside, I have seen your abominations. Woe to you, Jerusalem! {How long will you continue to be unclean}?"

As the remembering of their children, [so is the remembering of] their altars and their poles of Asherah worship beside [the] leafy trees on [the] high hills.

And I will restore Israel to its pasture, and it will feed [on] Carmel, and [in] Bashan, and on the hills of Ephraim, and [in] Gilead its hunger will be satisfied.
