1. For the Conductor, with instrumental music, a maskil by David,
2. when the Ziphites came and said to Saul, "Behold, David is hiding among us!”
3. O God, deliver me by Your Name, and vindicate me by Your might.
4. God, hear my prayer, listen to the words of my mouth.
5. For strangers have risen against me, and ruthless men have sought my soul; they are not mindful of God, 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. Behold, God is my helper; my Lord is with those who support my soul.
7. He will repay the evil of my watchful enemies; destroy them by Your truth.
8. With a free-will offering I will sacrifice to You; I will offer thanks to Your Name, O Lord, for it is good.
9. For He has saved me from every trouble, and my eye has seen [the downfall of] my enemy.
