Psalm 39:4-6 21st Century King James Version (KJ21)
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 a handbreadth, and mine age is as nothing before Thee; verily every man in his best state is altogether vanity. Selah
6 “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.
