1. A psalm by David. O Lord, hear my prayer, lend Your ear to my supplications. With Your faithfulness answer me, and with Your righteousness.
2. Do not enter into judgment with Your servant, for no living being would be vindicated before You.
3. For the enemy has pursued my soul; he has crushed my life to the ground; he has set me down in dark places, like those who are eternally dead.
4. Then my spirit became faint within me; my heart was dismayed within me.
5. I remembered the days of old; I meditated on all Your deeds; I spoke of Your handiwork.

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. I spread out my hands to You; like a languishing land my soul yearns after You, Selah.
7. Answer me soon, O Lord, my spirit is spent; hide not Your face from me, lest I become like those who descend into the pit.
8. Let me hear Your kindness in the morning, for have I trusted in You. Let me know the way in which I should walk, for to You I have lifted my soul.
9. Deliver me from my enemies, O Lord. I have concealed [my troubles from all, save] You.
10. Teach me to do Your will, for You are my God. Let Your good spirit lead me in an even path.
11. For the sake of Your Name, O Lord, give me life; in Your righteousness, take my soul out of distress.
12. And in Your kindness, cut off my enemies and obliterate all those who oppress my soul, for I am Your servant.
