Take heed to yourself that you do not offer your burnt offerings in every place that you see.

Take heed to yourself that you do not forsake the Levite as long as you live on the earth.

take heed to yourself that you do not become snared by following them, after they are destroyed from before you, and that you do not ask about their gods, saying, How did these nations serve their gods, that I too may do likewise?

And Moses and the priests the Levites spoke to all Israel, saying: Take heed and listen, O Israel. Today you have become the people of Jehovah your God.
