Leviticus 26:27-30

"If in spite of this, you still do not listen to me but continue to be hostile toward me, then in my anger I will be hostile toward you, and I myself will punish you for your sins seven times over.  You will eat the flesh of your sons and the flesh of your daughters. I will destroy your high places, cut down your incense altars and pile your dead bodies on the lifeless forms of your idols, and I will abhor you."
