1. For the Conductor, a song, a psalm. Raise your voices in jubilation to God, all the earth!
2. Sing the glory of His Name; make glorious His praise.
3. Say to God, "How awesome are Your deeds!" Because of Your great strength, Your enemies will [admit] their treachery to You.
4. All the earth will bow to You, and sing to You; they will sing praise to Your Name forever!
5. Go and see the works of God, awesome in His deeds toward mankind.

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 turned the sea into dry land, and they passed through the river on foot; we rejoiced in Him there.
7. He rules the world with His might, and His eyes watch the nations; let the rebellious not exalt themselves, Selah.
8. Bless our God, O nations, and let the voice of His praise be heard.
9. He has kept us alive, and did not allow our feet to falter.
10. For You tested us, O God; You refined us as one refining silver.
11. You brought us into prison; You placed a chain upon our loins.
12. You mounted men over our head; we went through fire and water, and You brought us out to abundance.
13. I will enter Your House with burnt-offerings, I will pay to You my vows,
14. which my lips uttered and my mouth spoke in my distress.
15. I will offer up to You burnt-offerings of fat animals, with the smoke of rams; I will prepare cattle with he-goats, Selah.
16. Come listen, all you who fear God, and I will relate what He has done for my soul.
17. I called to Him with my mouth, with exaltation beneath my tongue.
18. Had I seen iniquity in my heart, my Lord would not have listened.
19. But in truth, God heard; He gave ear to the voice of my prayer.
20. Blessed is God Who has not turned away my prayer or His kindness from me.
