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.
The 1611 reading
For it is not a vaine thing for you: because it is your life, and through this thing yee shall prolong your dayes, in the land whither yee goe ouer Iordan to possesse it.
