Deuteronomy 29:18-19

18So be very careful that you do not turn away from the Lord our God to worship the gods of those nations. No man, woman, clan or tribe among you must ever want to do that. That would be like the root of a plant that gives fruits which are full of poison.

19Nobody who hears the message of this covenant should think that they can go against it. Someone might say to himself, ‘I do not have to obey this covenant. I will be safe, whatever happens. God will still bless me.’ A person who thinks like that will bring trouble on everyone and on everything.
