1. For the Conductor, on the shoshanim,1 by David.
2. Deliver me, O God, for the waters have reached until my soul!
3. I have sunk in muddy depths without foothold; I have come into deep waters, and the current sweeps me away.
4. I am wearied by my crying, my throat is parched; my eyes pined while waiting for my God.
5. More numerous than the hairs on my head are those who hate me without reason. Mighty are those who would cut me off, those who are my enemies without cause. What I have not stolen, I will then have to return.

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. O God, You know my folly, and my wrongs are not hidden from You.
7. Let not those who hope in You be shamed through me, O my Lord, God of Hosts; let not those who seek You be disgraced through me, O God of Israel,
8. because for Your sake I have borne humiliation, disgrace covers my face.
9. I have become a stranger to my brothers, an alien to my mother's sons,
10. for the envy of Your House has consumed me, and the humiliations of those who scorn You have fallen upon me.
11. And I wept while my soul fasted, and it was a humiliation to me.
12. I made sackcloth my garment, and became a byword for them.
13. Those who sit by the gate speak of me, and [of me] are the songs of drunkards.
14. May my prayer to You, Lord, be at a gracious time; God, in Your abounding kindness, answer me with Your true deliverance.
15. Rescue me from the mire, so that I not sink; let me be saved from my enemies and from deep waters.
16. Let not the current of water sweep me away, nor the deep swallow me; and let not the pit close its mouth over me.
17. Answer me, Lord, for Your kindness is good; according to Your abundant mercies, turn to me.
18. Do not hide Your face from Your servant, for I am in distress-hurry to answer me.
19. Draw near to my soul and liberate it; redeem me, so that my enemies [not feel triumphant].
20. You know my humiliation, my shame, and my disgrace; all my tormentors are before You.
21. Humiliation has broken my heart, and I have become ill. I longed for comfort, but there was none; for consolers, but I did not find.
22. They put gall into my food, and for my thirst they gave me vinegar to drink.
23. Let their table become a trap before them, and [their] serenity, a snare.
24. Let their eyes be darkened so that they cannot see, and let their loins continually falter.
25. Pour Your wrath upon them, and let the fierceness of Your anger overtake them.
26. Let their palace be desolate, let there be no dweller in their tents,
27. for they persecute the one whom You struck, and tell of the pain of Your wounded ones.
28. Add iniquity to their iniquity, and let them not enter into Your righteousness.
29. May they be erased from the Book of Life, and let them not be inscribed with the righteous.
30. But I am poor and in pain; let Your deliverance, O God, streng-then me.
31. I will praise the Name of God with song, I will extol Him with thanksgiving!
32. And it will please the Lord more than [the sacrifice of] a mature bull with horns and hooves.
33. The humble will see it and rejoice; you seekers of God, [see] and your hearts will come alive.
34. For the Lord listens to the needy, and He does not despise His prisoners.
35. Let heaven and earth praise Him, the seas and all that moves within them,
36. for God will deliver Zion and build the cities of Judah, and they will settle there and possess it;
37. and the seed of His servants will inherit it, and those who love His Name will dwell in it.
