'High Place' in the Bible

They make offerings on the tops of mountains, burning perfumes in high places, under trees of every sort, because their shade is good: and so your daughters are given up to loose ways and your brides are false to their husbands.

The high places also of Aven, the sin of Israel, shall be destroyed: the thorn and the thistle shall come up on their altars; and they shall say to the mountains, Cover us; and to the hills, Fall on us.
