Deuteronomy 12:29-32

“When the LORD your God cuts off before you the nations which you are going in to dispossess, and you dispossess them and dwell in their land, beware that you are not ensnared to follow them, after they are destroyed before you, and that you do not inquire after their gods, saying, ‘How do these nations serve their gods, that I also may do likewise?’ You shall not behave thus toward the LORD your God, for every abominable act which the LORD hates they have done for their gods; for they even burn their sons and daughters in the fire to their gods. “Whatever I command you, you shall be careful to do; you shall not add to nor take away from it.
