1. For the Conductor, on the yedutun,1 by Asaph, a psalm.
2. [I raise] my voice to God and cry out; [I raise] my voice to God and He will listen to me.
3. On the day of my distress I sought my Lord. My wound oozes at night and does not abate; my soul refuses to be consoled.
4. I remember God and I moan; I speak and my spirit faints, Selah.
5. You grasped my eyelids; I am broken, I cannot speak.

Tehillim Ohel Yoseph Yitzchok (Kehot Publication Society)

Tehillim is recited by Jewish people collectively and individually, as the desire occurs to offer praise and thanksgiving to G-d; or alternitavely, in times of crisis and need, as a form of supplication, and even as a venue to express regret for sin.

6. I think of olden days, of ancient years.
7. During the night I recall my music, I meditate with my heart, and my spirit searches:
8. Is it for eternity that my Lord forsakes [me], nevermore to be appeased?
9. Has His kindness ceased forever? Has He sealed the decree for all generations?
10. Has God forgotten mercy? Has He in anger restrained His compassion forever?
11. I said, "It is to terrify me that the right hand of the Most High changes.”
12. I remember the deeds of Yah, when I remember Your wonders of long ago.
13. I meditate on all Your works, and speak of Your deeds.
14. O God, Your way is in sanctity; what god is as great as God?
15. You are the God Who works wonders; You make Your might known among the nations.
16. You redeemed Your people with a mighty arm, the children of Jacob and Joseph, Selah.
17. The waters2 saw You, O God, the waters saw You and trembled; even the deep shuddered.
18. The clouds streamed water, the heavens sounded forth, even Your arrows flew about.
19. The sound of Your thunder was in the rolling wind; lightning lit up the world; the earth trembled and quaked.
20. Your way was through the sea, Your path through the mighty waters; and Your footsteps were not known.3
21. You led Your people like a flock, by the hand of Moses and Aaron
