1. For the Conductor, on the neginat, by David.
2. Hear my cry, O God, listen to my prayer.
3. From the end of the earth I call to You, when my heart is faint [with trouble]: Lead me upon the rock that surpasses me!
4. For You have been a refuge for me, a tower of strength in the face of the enemy.
5. I will dwell in Your tent forever; I will take refuge in the shelter of Your wings, 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. For You, God, heard my vows; You granted the inheritance of those who fear Your Name.
7. Add days to the days of the king; may his years equal those of every generation.
8. May he sit always before God; appoint kindness and truth to preserve him.
9. Thus will I sing the praise of Your Name forever, as I fulfill my vows each day.
