Psalm 39:3-5

King James Version

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.
