Psalms 39:2-6

I was dumb with silence, I held my peace, even from good; And my sorrow was stirred. My heart was hot within me; While I was musing the fire burned; Then spake I with my tongue: Jehovah, make me to know mine end, And the measure of my days, what it is; Let me know how frail I am. Behold, thou hast made my days as handbreadths; And my life-time is as nothing before thee: Surely every man at his best estate is altogether vanity. [Selah Surely every man walketh in a vain show; Surely they are disquieted in vain: He heapeth up riches, and knoweth not who shall gather them.
