'Hills' in the Bible

Truly, the hills, and the noise of an army on the mountains, are a false hope: truly, in the Lord our God is the salvation of Israel.

For a voice is sounding from Dan, giving out evil from the hills of Ephraim:

Looking at the mountains, I saw them shaking, and all the hills were moved about.

I have seen your disgusting acts, even your false behaviour and your cries of desire and your loose ways on the hills in the field. Unhappy are you, O Jerusalem, you have no desire to be made clean; how long will you be in turning back to me?

Their altars and their wood pillars under every branching tree, on the high hills and the mountains in the field.

For there will be a day when those who get in the grapes on the hills of Ephraim will be crying, Up! let us go up to Zion to the Lord our God.

And I will make Israel come back to his resting-place, and he will get his food on Carmel and Bashan, and have his desire in full measure on the hills of Ephraim and in Gilead.
