1. A song of ascents. O Lord, remember unto David all his suffering,
2. how he swore to the Lord, and vowed to the Mighty Power of Jacob:
3. "I will not enter into the tent of my house; I will not go up into the bed that is spread for me;
4. I will not give sleep to my eyes, nor slumber to my eyelids;
5. until I will have found a place for the Lord, a resting place for the Mighty Power of Jacob.”

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. Lo, we heard of it in Ephrath; we found it in the field of the forest.
7. We will come to His resting places; we will prostrate ourselves at His footstool.
8. Ascend, O Lord, to Your resting place, You and the Ark of Your might.
9. May Your priests clothe themselves in righteousness, and may Your pious ones sing joyous songs.
10. For the sake of David Your servant, turn not away the face of Your anointed.
11. For the Lord has sworn to David a truth from which He will never retreat: "From the fruit of your womb will I set for you upon the throne.
12. If your sons will keep My covenant and this testimony of mine which I will teach them, then their sons, too, will sit on the throne for you until the end of time.
13. For the Lord has chosen Zion; He has desired it for His habitation.
14. This is My resting place to the end of time. Here will I dwell, for I have desired it.
15. I will abundantly bless her sustenance; I will satisfy her needy with bread.
16. I will clothe her priests with salvation, and her pious ones will sing joyous songs.
17. There I will cause David's power to flourish; there I have prepared a lamp for My anointed.
18. His enemies will I clothe with shame, but upon him, his crown will blossom."
