1. A prayer by David. Lord, turn Your ear, answer me, for I am poor and needy.
2. Guard my soul, for I am pious; You, my God, deliver Your servant who trusts in You.
3. Be gracious to me, my Lord, for to You I call all day.
4. Bring joy to the soul of Your servant, for to You, my Lord, I lift my soul.
5. For You, my Lord, are good and forgiving, and exceedingly kind to all who call upon You.

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. Lord, hear my prayer and listen to the voice of my supplications.
7. On the day of my distress I call upon You, for You will answer me.
8. There is none like You among the supernal beings, my Lord, and there are no deeds like Yours.
9. All the nations that You have made will come and bow down before You, my Lord, and give honor to Your Name,
10. for You are great and perform wonders, You alone, O God.
11. Lord, teach me Your way that I may walk in Your truth; unify my heart to fear Your Name.
12. I will praise You, my Lord, my God, with all my heart, and give honor to Your Name forever.
13. For Your kindness to me has been great; You have saved my soul from the depth of the grave.
14. O God, malicious men have risen against me; a band of ruthless men has sought my soul; they are not mindful of You.
15. But You, my Lord, are a compassionate and gracious God, slow to anger and abounding in kindness and truth.
16. Turn to me and be gracious to me; grant Your strength to Your servant, and deliver the son of Your maidservant.
17. Show me a sign of favor, that my foes may see and be shamed, because You, Lord, have given me aid and consoled me.
