1. For the Conductor, a psalm by David.
2. The king rejoices in Your strength, Lord; how greatly he exults in Your deliverance!
3. You have given him his heart's desire, and You have never withheld the utterance of his lips.
4. You preceded him with blessings of good; You placed a crown of pure gold on his head.
5. He asked of You life, You gave it to him-long life, forever and ever.

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. His glory is great in Your deliverance; You have placed majesty and splendor upon him.
7. For You make him a blessing forever; You gladden him with the joy of Your countenance.
8. For the king trusts in the Lord, and in the kindness of the Most High-that he will not falter.
9. Your hand will suffice for all Your enemies; Your right hand will find those who hate You.
10. You will make them as a fiery furnace at the time of Your anger. May the Lord consume them in His wrath; let a fire devour them.
11. Destroy their offspring from the earth, their descendants from mankind.
12. For they intended evil against You, they devised evil plans which they cannot execute.
13. For You will set them as a portion apart; with Your bowstring You will aim at their faces.
14. Be exalted, O Lord, in Your strength; we will sing and chant the praise of Your might.
