Psalm 39:4-6 New Revised Standard Version Catholic Edition (NRSVCE)
4 “Lord, let me know my end,
and what is the measure of my days;
let me know how fleeting my life is.
5 You have made my days a few handbreadths,
and my lifetime is as nothing in your sight.
Surely everyone stands as a mere breath.Selah
6 Surely everyone goes about like a shadow.
Surely for nothing they are in turmoil;
they heap up, and do not know who will gather.
