The word of the Lord came to me:
O mortal, set your face toward the mountains of Israel, and prophesy against them,
and say, You mountains of Israel, hear the word of the Lord God! Thus says the Lord God to the mountains and the hills, to the ravines and the valleys: I, I myself will bring a sword upon you, and I will destroy your high places.
Your altars shall become desolate, and your incense stands shall be broken; and I will throw down your slain in front of your idols.
I will lay the corpses of the people of Israel in front of their idols; and I will scatter your bones around your altars.
Wherever you live, your towns shall be waste and your high places ruined, so that your altars will be waste and ruined, your idols broken and destroyed, your incense stands cut down, and your works wiped out.
References for Ezekiel 6:6
The slain shall fall in your midst; then you shall know that I am the Lord.
