1. Praise the Lord! Praise the Lord, O my soul.
2. I will sing to the Lord with my soul; I will chant praises to my God while I yet exist.
3. Do not place your trust in nobles, nor in mortal man who has not the ability to bring deliverance.
4. When his spirit departs, he returns to his earth; on that very day, his plans come to naught.
5. Fortunate is he whose help is the God of Jacob, whose hope rests upon the Lord his God.

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 makes the heavens, the earth, the sea, and all that is in them; He keeps His promise faithfully forever.
7. He renders justice to the oppressed; He gives food to the hungry; the Lord releases those who are bound.
8. The Lord opens the eyes of the blind; the Lord straightens those who are bowed; the Lord loves the righteous.
9. The Lord watches over the strangers; He gives strength to orphan and widow; He thwarts the way of the wicked.
10. The Lord shall reign forever, your God, O Zion, throughout all generations. Praise the Lord!
