'Altars' in the Bible

And your altars shall be desolate, and your images shall be broken: and I will cast down your slain men before your idols.

And I will lay the dead carcases of the children of Israel before their idols; and I will scatter your bones round about your altars.

In all your dwellingplaces the cities shall be laid waste, and the high places shall be desolate; that your altars may be laid waste and made desolate, and your idols may be broken and cease, and your images may be cut down, and your works may be abolished.

Then shall ye know that I am the LORD, when their slain men shall be among their idols round about their altars, upon every high hill, in all the tops of the mountains, and under every green tree, and under every thick oak, the place where they did offer sweet savour to all their idols.
