Deuteronomy 32:47 Meaning and Commentary

Deuteronomy 32:47

For it [is] not a vain thing for you
That is, the law is not, and the observance of it in them and their children; it was no light and trifling matter, but of great importance and consequence, obedience to it being attended with rewards, and disobedience with punishment:

because it [is] your life:
if obeyed, the means of a comfortable and happy life, in the enjoyment of all good things, of the preservation and continuance of it to a length of time; and long life was always reckoned a great temporal mercy:

and through this thing ye shall prolong [your] days in the land
whither you go over Jordan to possess it;
that is, through their obedience to the law they should live long in the land of Canaan, which they were just going to possess; which explains what is meant by its being their life; their comfortable living and continuance in the land depended on their obedience to the law; see ( Isaiah 1:19 Isaiah 1:20 ) .

Deuteronomy 32:47 In-Context

45 When he had finished speaking all these words to all Isra'el,

46 he said to them, "Take to heart all the words of my testimony against you today, so that you can use them in charging your children to be careful to obey all the words of this Torah.

47 For this is not a trivial matter for you; on the contrary, it is your life! Through it you will live long in the land you are crossing the Yarden to possess."

48 That same day ADONAI said to Moshe,

49 "Go up into the 'Avarim Range, to Mount N'vo, in the land of Mo'av across from Yericho; and look out over the land of Kena'an, which I am giving the people of Isra'el as a possession.
