Psalms 39:5

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

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

⁵  Behold, 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.

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

⁷  And now, Lord, what wait I for? my hope is in thee.
