1. For the Conductor, by David. The fool says in his heart, "There is no God!" [Man's] deeds have become corrupt and abominable, no one does good.
2. The Lord looked down from heaven upon mankind, to see if there was any wise man who searches for God.
3. They have all gone astray together, they have become corrupt; there is none who does good, not even one.
4. Indeed, all the evildoers, who devour My people as they devour bread, who do not call upon the Lord, will [ultimately] come to know [the consequences of their actions].
5. There they will be seized with fright, for God is with the righteous generation.

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. You scorn the counsel of the lowly, that he puts his trust in the Lord.
7. O that out of Zion would come Israel's deliverance! When the Lord returns the captivity of His people, Jacob will exult, Israel will rejoice.
