Deuteronomy 32:15-19

ISV(i) 15 Israel’s RebellionJacob dined until satisfied; Jeshurun grew fat and kicked. He grew fat, coarse, and gross, so that he abandoned the God who made him and spurned the Rock that was his salvation. 16 They provoked him to jealousy over foreigners and to anger over detestable things. 17 They sacrificed to demons— not to the real God— gods whom they didn’t know, new neighbors who had recently appeared, whom your ancestors never feared. 18 You neglected the Rock that fathered you; you abandoned God, who was awaiting your birth.
19 The LORD’s ResponseThe LORD saw it and became jealous, provoked by his sons and daughters.
