Psalms 39:3-6

3My heart was hot within me; While I was musing, the fire burned. Then I spoke with my tongue:

4“Lord, make me to know my end, And what is the measure of my days, That I may know how frail I am.

5Indeed, You have made my days as handbreadths, And my age is as nothing before You; Certainly every man at his best state is but vapor. Selah

6Surely every man walks about like a shadow; Surely they busy themselves in vain; He heaps up riches, And does not know who will gather them.
