1. Praise the Lord! Praise the Lord for He is good, for His kindness is everlasting.
2. Who can recount the mighty acts of the Lord, or proclaim all His praises?
3. Fortunate are those who preserve justice, who perform deeds of righteousness all the time.
4. Remember me, Lord, when You find favor with Your people; be mindful of me with Your deliverance;
5. to behold the prosperity of Your chosen, to rejoice in the joy of Your nation, to glory with Your inheritance.

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. We have sinned as did our fathers, we have acted perversely and wickedly.
7. Our fathers in Egypt did not contemplate Your wonders, they did not remember Your abundant kindnesses, and they rebelled by the sea, at the Sea of Reeds.
8. Yet He delivered them for the sake of His Name, to make His strength known.
9. He roared at the Sea of Reeds and it dried up; He led them through the depths, as through a desert.
10. He saved them from the hand of the enemy, and redeemed them from the hand of the foe.
11. The waters engulfed their adversaries; not one of them remained.
12. Then they believed in His words, they sang His praise.
13. They quickly forgot His deeds, they did not wait for His counsel;
14. and they lusted a craving in the desert, they tested God in the wilderness.
15. And He gave them their request, but sent emaciation into their souls.
16. They angered Moses in the camp, and Aaron, the Lord's holy one.
17. The earth opened and swallowed Dathan, and engulfed the company of Abiram;
18. and a fire burned in their assembly, a flame set the wicked ablaze.
19. They made a calf in Horeb, and bowed down to a molten image.
20. They exchanged their Glory for the likeness of a grass-eating ox.
21. They forgot God, their savior, Who had performed great deeds in Egypt,
22. wonders in the land of Ham, awesome things at the Sea of Reeds.
23. He said that He would destroy them-had not Moses His chosen one stood in the breach before Him, to turn away His wrath from destroying.
24. They despised the desirable land, they did not believe His word.
25. And they murmured in their tents, they did not heed the voice of the Lord.
26. So He raised His hand [in oath] against them, to cast them down in the wilderness,
27. to throw down their progeny among the nations, and to scatter them among the lands.
28. They joined themselves to [the idol] Baal Peor, and ate of the sacrifices to the dead;
29. they provoked Him with their doings, and a plague broke out in their midst.
30. Then Phineas arose and executed judgement, and the plague was stayed;
31. it was accounted for him as a righteous deed, through all generations, forever.
32. They angered Him at the waters of Merivah, and Moses suffered on their account;
33. for they defied His spirit, and He pronounced [an oath] with His lips.
34. They did not destroy the nations as the Lord had instructed them;
35. rather, they mingled with the nations and learned their deeds.
36. They worshipped their idols, and they became a snare for them.
37. They sacrificed their sons and daughters to demons.
38. They spilled innocent blood, the blood of their sons and daughters whom they sacrificed to the idols of Canaan; and the land became guilty with blood.
39. They were defiled by their deeds, and went astray by their actions.
40. And the Lord's wrath blazed against His people, and He abhorred His inheritance;
41. so He delivered them into the hands of nations, and their enemies ruled them.
42. Their enemies oppressed them, and they were subdued under their hand.
43. Many times did He save them, yet they were rebellious in their counsel and were impoverished by their sins.
44. But He saw their distress, when He heard their prayer;
45. and He remembered for them His covenant and He relented, in keeping with His abounding kindness,
46. and He caused them to be treated mercifully by all their captors.
47. Deliver us, Lord our God; gather us from among the nations, that we may give thanks to Your Holy Name and glory in Your praise.
48. Blessed is the Lord, the God of Israel, forever and ever. And let all the people say, "Amen! Praise the Lord!"
