Psalm 39 (ESV)
To the choirmaster: to Jeduthun. A Psalm of David.

1 I said, “I will guard my ways,
    that I may not sin with my tongue;
I will guard my mouth with a muzzle,
    so long as the wicked are in my presence.”
2 I was mute and silent;
    I held my peace to no avail,
and my distress grew worse.
3    My heart became hot within me.
As I mused, the fire burned;
    then I spoke with my tongue:

4 “O Lord, make me know my end
    and what is the measure of my days;
    let me know how fleeting I am!
5 Behold, you have made my days a few handbreadths,
    and my lifetime is as nothing before you.
Surely all mankind stands as a mere breath! Selah
6    Surely a man goes about as a shadow!
Surely for nothing they are in turmoil;
    man heaps up wealth and does not know who will gather!

7 “And now, O Lord, for what do I wait?
    My hope is in you.
8 Deliver me from all my transgressions.
    Do not make me the scorn of the fool!
9 I am mute; I do not open my mouth,
    for it is you who have done it.
10 Remove your stroke from me;
    I am spent by the hostility of your hand.
11 When you discipline a man
    with rebukes for sin,
you consume like a moth what is dear to him;
    surely all mankind is a mere breath! Selah

12 “Hear my prayer, O Lord,
    and give ear to my cry;
    hold not your peace at my tears!
For I am a sojourner with you,
    a guest, like all my fathers.
13 Look away from me, that I may smile again,
    before I depart and am no more!”
