Deuteronomy 30:15-18

15“Now listen! Today I am giving you a choice between life and death, between prosperity and disaster.

16For I command you this day to love the Lord your God and to keep his commands, decrees, and regulations by walking in his ways. If you do this, you will live and multiply, and the Lord your God will bless you and the land you are about to enter and occupy.

17“But if your heart turns away and you refuse to listen, and if you are drawn away to serve and worship other gods,

18then I warn you now that you will certainly be destroyed. You will not live a long, good life in the land you are crossing the Jordan to occupy.
