'Mountains' in the Bible

They sacrifice on the tops of the mountainsAnd burn incense on the hills,Under oaks, poplars, and terebinths,Because the shade is pleasant there.Therefore your daughters play the prostituteAnd your brides commit adultery.

Also the high places of Aven (Beth-aven), the sin of Israel, will be destroyed;The thorn and the thistle will grow on their [pagan] altars,And [in despair] they will say to the mountains,“Cover us!” And to the hills, “Fall on us!”
