“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.”
1611 King James Version (KJV)
32:47 Not vain - It is not an unprofitable or contemptible work I advise you to, but well worthy of your most serious care.
