Ezekiel 6:13 in the King James Version
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.
Context
12 He who is far off will die of the pestilence. He who is near will fall by the sword. He who remains and is besieged will die by the famine. Thus I will accomplish my wrath on them.
13 You will know that I am the LORD when their slain men are among their idols around their altars, on every high hill, on all the tops of the mountains, under every green tree, and under every thick oak—the places where they offered pleasant aroma to all their idols.
14 I will stretch out my hand on them and make the land desolate and waste, from the wilderness toward Diblah, throughout all their habitations. Then they will know that I am the LORD.’”
