'Hills' in the Bible

Truly in vain is [the help that is looked for] from the hills, the tumult on the mountains. Truly the salvation of Israel is in Yahweh our God.

For a voice declares from Dan, and publishes evil from the hills of Ephraim:

I saw the mountains, and behold, they trembled, and all the hills moved back and forth.

I have seen your abominations, even your adulteries, and your neighing, the lewdness of your prostitution, on the hills in the field. Woe to you, Jerusalem! You will not be made clean; how long shall it yet be?

while their children remember their altars and their Asherim by the green trees on the high hills.

For there shall be a day, that the watchmen on the hills of Ephraim shall cry, Arise, and let us go up to Zion to Yahweh our God.

I will bring Israel again to his pasture, and he shall feed on Carmel and Bashan, and his soul shall be satisfied on the hills of Ephraim and in Gilead.
