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.

For they are not commanded you in vain, but that every one should live in them, and that doing them you may continue a long time in the land whither you are going over the Jordan to possess it.

For it is no vain word for you, but it is your life, and through this word ye shall prolong your days on the land whereunto ye pass over the Jordan to possess it.

for it is not a vain thing for you, for it is your life, and by this thing ye prolong days on the ground whither ye are passing over the Jordan to possess it.'

And this is no small thing for you, but it is your life, and through this you may make your days long in the land which you are going over Jordan to take for your heritage.

For these things have not been entrusted to you to no purpose, but so that each one would live by them, and so that, in doing these, you may continue for a long time in the land, which you will enter upon crossing the Jordan in order to possess it."

Non enim verbum hoc inane a vobis, sed est vita vestra, et per hoc verbum prolongabitis dies super terram ad quam possidendam vos transitis Jordanem.

Through this thing ye shall prolong your days - Instead of being cut off, as God here threatens, ye shall be preserved and rendered prosperous in the land which, when they passed over Jordan, they should possess.

For it [is] not a (x) 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.
(x) For I will perform my promise to you, (Isaiah 55:10).

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.

Not vain - It is not an unprofitable or contemptible work I advise you to, but well worthy of your most serious care.
