Deuteronomy 32:19-21

19 "When the LORD saw this, he was angry and rejected his sons and daughters.

20 'I will no longer help them,' he said; 'then I will see what happens to them, those stubborn, unfaithful people.

21 With their idols they have made me angry, jealous with their so-called gods, gods that are really not gods. So I will use a so-called nation to make them angry; I will make them jealous with a nation of fools.
