Psalms 39:2-6

I was mute with silence, I held my peace even from good; And my sorrow was stirred up. My heart was hot within me; While I was musing, the fire burned. Then I spoke with my tongue: “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 as nothing before You; Certainly every man at his best state is but vapor. Selah Surely 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.
