Deuteronomy 12:28-32 New Revised Standard Version (NRSV)
28 Be careful to obey all these words that I command you today,[a] so that it may go well with you and with your children after you forever, because you will be doing what is good and right in the sight of the Lord your God.
Warning against Idolatry
29 When the Lord your God has cut off before you the nations whom you are about to enter to dispossess them, when you have dispossessed them and live in their land, 30 take care that you are not snared into imitating them, after they have been destroyed before you: do not inquire concerning their gods, saying, “How did these nations worship their gods? I also want to do the same.” 31 You must not do the same for the Lord your God, because every abhorrent thing that the Lord hates they have done for their gods. They would even burn their sons and their daughters in the fire to their gods. 32 [b] You must diligently observe everything that I command you; do not add to it or take anything from it.
