Psalm 39:4-6

New Revised Standard Version, Anglicised Catholic Edition

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.
