Psalms 39:4-6

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.
