Deuteronomy 32: 18 - 21
18 You were unmindful of the Rock that begot you, and you forgot the God who gave you birth.
19 "The LORD saw it, and spurned them, because of the provocation of his sons and his daughters.
20 And he said, `I will hide my face from them, I will see what their end will be, for they are a perverse generation, children in whom is no faithfulness.
21 They have stirred me to jealousy with what is no god; they have provoked me with their idols. So I will stir them to jealousy with those who are no people; I will provoke them with a foolish nation.
