They sacrificed unto demons, which were no God, To gods that they knew not, To new gods that came up of late, Which your fathers dreaded not.

They made offerings to evil spirits which were not God, to gods who were strange to them, which had newly come up, not feared by your fathers.

εθυσιασαν εις δαιμονια, ουχι εις τον Θεον· εις θεους, τους οποιους δεν εγνωριζον, εις νεους θεους νεωστι εισαχθεντας, τους οποιους δεν ελατρευον οι πατερες σας·

They sacrificed unto devils, not to God; to gods whom they knew not, to new gods that came newly up, whom your fathers feared not.
