1. For the Conductor, on the gittit,1 a psalm by the sons of Korach.
2. How beloved are Your dwellings, O Lord of Hosts!
3. My soul yearns, indeed it pines, for the courtyards of the Lord; my heart and my flesh [long to] sing to the living God.
4. Even the bird has found a home, and the swallow a nest for herself, where she lays her young on the [ruins of] Your altars, O Lord of Hosts, my King and my God.
5. Fortunate are those who dwell in Your House; they will yet praise You forever.

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. Fortunate is the man whose strength is in You; the paths [to the Temple] are in his heart.
7. For those who pass through the Valley of Thorns, He places wellsprings; their guide will be cloaked in blessings.2
8. They go from strength to strength; they will appear before God in Zion.
9. O Lord, God of Hosts, hear my prayer; listen, O God of Jacob, forever.
10. See our shield,3 O God, and look upon the face of Your anointed one.
11. For better one day in Your courtyards than a thousand [elsewhere]. I would rather stand at the threshold of the house of my God, than dwell [in comfort] in the tents of wickedness.
12. For the Lord, God, is a sun and a shield; the Lord bestows favor and glory; He does not withhold goodness from those who walk in innocence.
13. O Lord of Hosts! Fortunate is the man who trusts in You.
