Psalm 39:4

2I was dumb with silence, I held my peace, even from good; and my sorrow was stirred.

3My heart was hot within me, while I was musing the fire burned: then spake I with my tongue,

4LORD, make me to know mine end, and the measure of my days, what it is: that I may know how frail I am.

5Behold, thou hast made my days as an handbreadth; and mine age is as nothing before thee: verily every man at his best state is altogether vanity. Selah.

6Surely every man walketh in a vain shew: surely they are disquieted in vain: he heapeth up riches, and knoweth not who shall gather them.
