For it is no vain thing for you; because it is your life, and through this thing you shall prolong your days in the land, where you go over the Jordan to possess it."

KJV

For it is not a vain thing for you; because it is your life: and through this thing ye shall prolong your days in the land, whither ye go over Jordan to possess it.

Commentary

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 an d 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 Isa 1:19 .
