1. For the Conductor, on the gittit,1 a psalm by David.
2. Lord, our Master, how mighty is Your Name throughout the earth, You Who has set Your majesty upon the heavens!
3. Out of the mouths of babes and sucklings You have established might, to counter Your enemies, to silence foe and avenger.2
4. When I behold Your heavens, the work of Your fingers, the moon and the stars which You have set in place—
5. what is man that You should remember him, son of man that You should be mindful of him?

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. Yet, You have made him but a little less than the angels, and crowned him with honor and glory.
7. You made him ruler over Your handiwork, You placed everything under his feet.
8. Sheep and cattle—all of them, also the beasts of the field;
9. the birds of the sky and the fish of the sea; all that traverses the paths of the seas.
10. Lord, our Master, how mighty is Your Name throughout the earth.
