1. A psalm by Asaph. God stands in the council of judges; among the judges He renders judgment:
2. How long will you judge wickedly, ever showing partiality toward the evildoers?
3. Render justice to the needy and the orphan; deal righteously with the poor and the destitute.
4. Rescue the needy and the pauper; deliver them from the hand of the wicked.
5. But they do not know, nor do they understand; they go about in darkness, [therefore] all the foundations of the earth tremble.

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. I said that you are angels, supernal beings, all of you;
7. but you will die as mortals, you will fall like any prince.
8. Arise, O God, judge the earth, for You possess all the nations.
