1. By David, a psalm. I will sing of [Your] kindness and justice; to You, O Lord, will I chant praise!
2. I will pay heed to the path of integrity-O when will it come to me? I shall walk with the innocence of my heart [even] within my house.
3. I shall not place an evil thing before my eyes; I despise the doing of wayward deeds, it does not cling to me.
4. A perverse heart shall depart from me; I shall not know evil.
5. He who slanders his fellow in secret, him will I cut down; one with haughty eyes and a lustful heart, him I cannot suffer.

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. My eyes are upon the faithful of the land, that they may dwell with me; he who walks in the path of integrity, he shall minister to me.
7. He that practices deceit shall not dwell within my house; the speaker of lies shall have no place before my eyes.
8. Every morning I will cut down all the wicked of the land, to excise all evildoers from the city of the Lord.
