Deuteronomy 12:30; Deuteronomy 12:31

30 take care that you be not ensnared to follow them, after they have been destroyed before you, and that you do not inquire about their gods, saying, 'How did these nations serve their gods?--that I also may do the same.'

31 You shall not worship the LORD your God in that way, for every abominable thing that the LORD hates they have done for their gods, for they even burn their sons and their daughters in the fire to their gods.
