'Hills' in the Bible

“Truly, [the hope of salvation from] the hill [where idols are worshiped] is a deception,A tumult and noisy multitude on the mountains;Truly in the Lord our GodIs the salvation of Israel.

I looked at the mountains, and behold, they were trembling,And all the hills moved back and forth.

“I have seen your vile and detestable acts,Even your adulteries and your lustful neighings [after idols],And the lewdness of your prostitutionOn the hills in the fields.Woe (judgment is coming) to you, O Jerusalem!How long will you remain unclean [by ignoring My precepts]?”

As they remember their children,So they remember [in detail] their [pagan] altars and their AsherimBeside green trees on the high hills.

“Go up [north] to Lebanon and cry out,And raise your voice in [the hills of] Bashan [across the Jordan];Cry out also from Abarim,For all your lovers (allies) have been destroyed.

“For there will be a day when the watchmenOn the hills of Ephraim cry out,‘Arise, and let us go up to Zion,To the Lord our God.’”

And I will bring Israel [home] again to his pasture and he will graze on [the most fertile lands of] Carmel [in the west] and Bashan [in the east], and his soul will be satisfied on the hills of Ephraim and Gilead.
