Psalm 39:4-6 Revised Standard Version Catholic Edition (RSVCE)
4 “Lord, let me know my end,
and what is the measure of my days;
let me know how fleeting my life is!
5 Behold, thou hast made my days a few handbreadths,
and my lifetime is as nothing in thy sight.
Surely every man stands as a mere breath!Selah
6 Surely man goes about as a shadow!
Surely for nought are they in turmoil;
man heaps up, and knows not who will gather!
