1. Praise the Lord! Praise the Lord from the heavens; praise Him in the celestial heights.
2. Praise Him, all His angels; praise Him, all His hosts.
3. Praise Him, sun and moon; praise Him, all the shining stars.
4. Praise Him, hea-ven of heavens, and the waters that are above the heavens.
5. Let them praise the Name of the Lord, for He comman-ded and they were created.

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. He has established them forever, for all time; He issued a decree, and it shall not be transgressed.
7. Praise the Lord from the earth, sea-monsters and all [that dwell in] the depths;
8. fire and hail, snow and vapor, stormy wind carrying out His command;
9. the mountains and all hills, fruit-bearing trees and all cedars;
10. the beasts and all cattle, creeping things and winged fowl;
11. kings of the earth and all nations, rulers and all judges of the land;
12. young men as well as maidens, elders with young lads.
13. Let them praise the Name of the Lord, for His Name is sublime, to Himself; its radiance [alone] is upon earth and heaven.
14. He shall raise the glory of His people, [increase] the praise of all His pious ones, the Children of Israel, the people close to Him. Praise the Lord!
