Deuteronomy 12:30

take heed to thyself that thou be not snared by following them, fall into the same snare of idolatry which caused their downfall, after that they be destroyed from before thee, for that judgment of the Lord should deter them from a similar foolhardy course; and that thou enquire not after their gods, saying, How did these nations serve their gods? Even so will I do likewise. They should not even inquire about the form of worship used by the heathen, lest they be tempted to try it for themselves.
