Lord, make me to know my end, and what is the measure of my days, that I may know how frail I am. Indeed, You have made my days as handbreadths, and my age is nothing before You; certainly every man at his best state is but a vapor. Surely every man walks about as a shadow; surely they busy themselves in vain; he heaps up riches, and does not know who will gather them.

Psalm 39:4-6
