Deuteronomy 32:15-18

15“But Israel soon became fat and unruly; the people grew heavy, plump, and stuffed! Then they abandoned the God who had made them; they made light of the Rock of their salvation.

16They stirred up his jealousy by worshiping foreign gods; they provoked his fury with detestable deeds.

17They offered sacrifices to demons, which are not God, to gods they had not known before, to new gods only recently arrived, to gods their ancestors had never feared.

18You neglected the Rock who had fathered you; you forgot the God who had given you birth.
