1. For the Conductor, on the shushan eidut. A michtam by David, to instruct,
2. when he battled with Aram Naharayim and Aram Tzovah, and Joab returned and smote Edom in the Valley of Salt, twelve thousand [men].
3. O God, You forsook us, You have breached us! You grew furious-restore us!
4. You made the earth quake, You split it apart-heal its fragments, for it totters!
5. You showed Your nation harshness, You gave us benumbing wine to drink.

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. [Now] give those who fear You a banner to raise themselves, for the sake of truth, Selah.
7. That Your beloved ones may be delivered, help with Your right hand and answer me.
8. God said with His Holy [Spirit] that I would exult; I would divide Shechem, and measure out the Valley of Succot.
9. Mine is Gilead, mine is Menasseh, and Ephraim is the stronghold of my head; Judah is my prince.
10. Moab is my washbasin, and upon Edom I will cast my shoe; for me, Philistia will sound a blast [of coronation].
11. Who will bring me into the fortified city? Who will lead me unto Edom?
12. Is it not You, God, Who has [until now] forsaken us, and did not go forth with our legions?
13. Grant us relief from the oppressor; futile is the salvation of man.
14. With God we will do valiantly, and He will trample our oppressors.
