1. A song, a psalm by the sons of Korach.
2. The Lord is great and exceedingly acclaimed in the city of God, His holy mountain.
3. Beautiful in landscape, the joy of the whole earth is Mount Zion, on the northern slopes, the city of the great King.
4. In her citadels, God became known as a tower of strength.
5. For behold, the kings assembled, they advanced in concert [to invade her].

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 saw [the wonders of the Almighty] and were astounded; they were terror-stricken, they hastened to flee.
7. Trembling seized them there, pangs as of a woman in the throes of labor;
8. [they were crushed as] by an east wind that shatters the ships of Tarshish.
9. As we have heard, so have we seen, in the city of the Lord of Hosts, in the city of our God; may God establish it for all eternity.
10. God, we have been hoping for Your kindness [to be revealed] within Your Sanctuary.
11. As Your Name, O God, [is great,] so is Your praise to the ends of the earth; Your right hand is filled with righteousness.
12. Let Mount Zion rejoice, let the towns of Judah exult, because of Your judgments.
13. Walk around Zion, encircle her, count her towers.
14. Consider well her ramparts, behold her lofty citadels, that you may recount it to a later generation.
15. For this God is our God forever and ever; He will lead us eternally.
