17 If, however, your heart turns away and you do not obey, but are led astray and bow down to other gods and serve them,
18 I tell you today that you will certainly perish; you will not have a long life on the land which you are crossing the Jordan to enter and possess.
19 I call heaven and earth today to witness against you: I have set before you life and death, the blessing and the curse. Choose life, then, that you and your descendants may live,
20 by loving the Lord, your God, obeying his voice, and holding fast to him. For that will mean life for you, a long life for you to live on the land which the Lord swore to your ancestors, to Abraham, Isaac, and Jacob, to give to them.
