1. For the Conductor, on the ayelet hashachar, a psalm by David.
2. My God, my God, why have You forsaken me! So far from saving me, from the words of my outcry?
3. My God, I call out by day, and You do not answer; at night-but there is no respite for me.
4. Yet You, Holy One, are enthroned upon the praises of Israel.
5. In You our fathers trusted; they trusted and You saved them.

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. They cried to You and were rescued; they trusted in You and were not shamed.
7. And I am a worm and not a man; scorn of men, contempt of nations.
8. All who see me mock me; they open their lips, they shake their heads.
9. But one that casts [his burden] upon the Lord-He will save him; He will rescue him, for He desires him.
10. For You took me out of the womb, and made me secure on my mother's breasts.
11. I have been thrown upon You from birth; from my mother's womb You have been my God.
12. Be not distant from me, for trouble is near, for there is none to help.
13. Many bulls surround me, the mighty bulls of Bashan encircle me.
14. They open their mouths against me, like a lion that ravages and roars.
15. I am poured out like water, all my bones are disjointed; my heart has become like wax, melted within my innards.
16. My strength is dried up like a potsherd, and my tongue cleaves to my palate; You set me in the dust of death.
17. For dogs surround me, a pack of evildoers enclose me; my hands and feet are like a lion's prey.
18. I count all my limbs, while they watch and gloat over me.
19. They divide my garments amongst them; they cast lots upon my clothing.
20. But You, Lord, do not be distant; my Strength, hurry to my aid!
21. Save my life from the sword, my soul from the grip of dogs.
22. Save me from the lion's mouth, as You have answered me from the horns of wild beasts.
23. I will recount [the praises of] Your Name to my brothers; I will extol You amidst the congregation.
24. You that fear the Lord, praise Him! Glorify Him, all you progeny of Jacob! Stand in awe of Him, all you progeny of Israel!
25. For He has not despised nor abhorred the entreaty of the poor, nor has He concealed His face from him; rather He heard when he cried to Him.
26. My praise comes from You, in the great congregation; I will pay my vows before those that fear Him.
27. Let the humble eat and be satisfied; let those who seek the Lord praise Him-may your hearts live forever!
28. All the ends of the earth will remember and return to the Lord; all families of nations will bow down before You.
29. For sovereignty is the Lord's, and He rules over the nations.
30. All the fat ones of the earth will eat and bow down, all who descend to the dust shall kneel before Him, but He will not revive their soul.
31. The progeny of those who serve Him will tell of the Lord to the latter generations.
32. They will come and relate His righteousness-all that He has done-to a newborn nation.
