A Warning against Idolatry
Once the nations are dispossessed, Israel must not ask how their gods were served or copy those rites for the LORD. Those practices are abominations, so the command must be kept without addition or subtraction.
W29hen the LORD your God cuts off before you the nations you are entering to dispossess, and you drive them out and live in their land, 30be careful not to be ensnared by their ways after they have been destroyed before you. Do not inquire about their gods, asking, “How do these nations serve their gods? I will do likewise.” 31You must not worship the LORD your God in this way, because they practice for their gods every abomination which the LORD hates. They even burn their sons and daughters in the fire as sacrifices to their gods. 32See that you do everything I command you; do not add to it or subtract from it.
