1. A psalm by David, when he was in the Judean desert.
2. O God, You are my Almighty, I seek You! My soul thirsts for You, my flesh longs for You; [like one] in a desolate and dry land, without water,
3. so [I thirst] to see You in the Sanctuary, to behold Your might and glory.
4. For Your kindness is better than life; my lips shall praise You.
5. Thus will I bless you all my life, in Your Name I will raise my hands [in prayer].

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. As with fat and abundance my soul is sated, when my mouth offers praise with expressions of joy.
7. Indeed, I remember You upon my bed; during the watches of the night I meditate upon You.
8. For You were a help for me; I sing in the shadow of Your wings.
9. My soul cleaved to You; Your right hand supported me.
10. But they seek desolation for my soul; they will enter the depths of the earth.
11. They will drag them by the sword; they will be the portion of foxes.
12. And the king will rejoice in God, and all who swear by Him will take pride, when the mouths of liars are blocked up.
