1. A maskil1 by Eitan the Ezrachite.
2. I will sing of the Lord's kindness forever; to all generations I will make known Your faithfulness with my mouth.
3. For I have said, "The world is built with kindness; there in the heavens You establish Your faithfulness.”
4. I have made a covenant with My chosen one; I have sworn to David, My servant:
5. "I will establish Your descendants forever; I will build your throne for all generations," Selah.

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. Then the heavens will extol Your wonders, O Lord; Your faithfulness, too, in the congregation of the holy ones.
7. Indeed, who in heaven can be compared to the Lord, who among the supernal beings can be likened to the Lord!
8. The Almighty is revered in the great assembly of the holy ones, awe-inspiring to all who surround Him.
9. O Lord, God of Hosts, who is mighty like You, O God! Your faithfulness surrounds You.
10. You rule the vastness of the sea; when its waves surge, You still them.
11. You crushed Rahav (Egypt) like a corpse; with Your powerful arm You scattered Your enemies.
12. Yours are the heavens, the earth is also Yours; the world and all therein-You established them.
13. The north and the south-You created them; Tabor and Hermon sing of [the greatness] of Your Name.
14. Yours is the arm which has the might; strengthen Your hand, raise high Your right hand.
15. Righteousness and justice are the foundation of Your throne; kindness and truth go before Your countenance.
16. Fortunate is the people who know the sound of the shofar; Lord, they walk in the light of Your countenance.
17. They rejoice in Your Name all day, and they are exalted through Your righteousness.
18. Indeed, You are the splendor of their might, and in Your goodwill our glory is exalted.
19. For our protectors turn to the Lord, and our king to the Holy One of Israel.
20. Then You spoke in a vision to Your pious ones and said: "I have granted aid to [David] the mighty one; I have exalted the one chosen from among the people.
21. I have found David, My servant; I have anointed him with My holy oil.
22. It is he whom My hand shall be prepared [to assist]; My arm, too, shall strengthen him.
23. The enemy shall not prevail over him, nor shall the iniquitous person afflict him.
24. And I will crush his adversaries before him, and will strike down those who hate him.
25. Indeed, My faithfulness and My kindness shall be with him, and through My Name his glory shall be exalted.
26. I will set his hand upon the sea, his right hand upon the rivers.
27. He will call out to Me, 'You are my Father, my God, the strength of my deliverance.’
28. I will also make him [My] firstborn, supreme over the kings of the earth.
29. I will maintain My kindness for him forever; My covenant shall remain true to him.
30. And I will bestow [kingship] upon his seed forever, and his throne will endure as long as the heavens last.
31. If his children forsake My Torah and do not walk in My ordinances;
32. if they profane My statutes and do not observe My commandments,
33. then I will punish their transgression with the rod and their misdeeds with plagues.
34. Yet I shall not take away My kindness from him, nor betray My faithfulness.
35. I will not abrogate My covenant, nor change that which has issued from My lips.
36. One thing I have sworn by My holiness-I will not cause disappointment to David.
37. His seed will endure forever and his throne will be [resplendent] as the sun before Me.
38. Like the moon, it shall be established forever; [the moon] is a faithful witness in the sky for all time.”
39. Yet You have forsaken and abhorred; You became enraged at Your anointed.
40. You annulled the covenant with Your servant; You have profaned his crown [by casting it] to the ground.
41. You shattered all his fences; You turned all his strongholds into ruin.
42. All wayfarers despoiled him; he has become a disgrace to his neighbors.
43. You have uplifted the right hand of his adversaries; You have made all his enemies rejoice.
44. You also turned back the blade of his sword, and did not sustain him in battle.
45. You put an end to his splendor, and toppled his throne to the ground.
46. You have cut short the days of his youth; You have enclothed him with long-lasting shame.
47. How long, O Lord, will You conceal Yourself-forever? [How long] will Your fury blaze like fire?
48. O remember how short is my life span! Why have You created all children of man for naught?
49. What man can live and not see death, can save his soul forever from the grave?
50. Where are Your former deeds of kindness, my Lord, which You swore to David in Your faithfulness?
51. Remember, my Lord, the disgrace of Your servants, that I bear in my bosom from all the many nations;
52. that Your enemies have disgraced, O Lord, that they have disgraced the footsteps of Your anointed.
53. Blessed is the Lord forever, Amen and Amen.
