Deuteronomy 30:18 Meaning and Commentary

Deuteronomy 30:18

I denounce unto, you this day that ye shall surely perish,
&c.] By one judgment or another; this he most solemnly averred, and it might be depended upon that it would certainly be their case; see ( Deuteronomy 4:26 ) ;

[and that] ye shall not prolong [your] days upon the land, whither
thou passest over Jordan to go to possess it;
but be cut short by death, of one kind or another, by sword, or famine, or pestilence, or be carried into captivity; one or other of which were frequently their case.

Deuteronomy 30:18 In-Context

16 If you obey the commands of the Lord your God, which I give you today, if you love him, obey him, and keep all his laws, then you will prosper and become a nation of many people. The Lord your God will bless you in the land that you are about to occupy.
17 But if you disobey and refuse to listen, and are led away to worship other gods,
18 you will be destroyed - I warn you here and now. You will not live long in that land across the Jordan that you are about to occupy.
19 I am now giving you the choice between life and death, between God's blessing and God's curse, and I call heaven and earth to witness the choice you make. Choose life.
20 Love the Lord your God, obey him and be faithful to him, and then you and your descendants will live long in the land that he promised to give your ancestors, Abraham, Isaac, and Jacob."
