Ps 137 (King James)

   ¹ By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion. ² We hanged our harps upon the willows in the midst thereof. ³ For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion. ⁴ How shall we sing the LORD's song in a strange land? ⁵ If I forget thee, O Jerusalem, let my right hand forget her cunning. ⁶ If I do not remember thee, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief joy.
   ⁷ Remember, O LORD, the children of Edom in the day of Jerusalem; who said, Rase it, rase it, even to the foundation thereof. ⁸ O daughter of Babylon, who art to be destroyed; happy shall he be, that rewardeth thee as thou hast served us. ⁹ Happy shall he be, that taketh and dasheth thy little ones against the stones.

Ps 137 (Vulgate)

   ¹ Ipsi David. [Confitebor tibi, Domine, in toto corde meo,
quoniam audisti verba oris mei.
In conspectu angelorum psallam tibi ;
   ² adorabo ad templum sanctum tuum,
et confitebor nomini tuo :
super misericordia tua et veritate tua ;
quoniam magnificasti super omne, nomen sanctum tuum.
   ³ In quacumque die invocavero te, exaudi me ;
multiplicabis in anima mea virtutem.
   ⁴ Confiteantur tibi, Domine, omnes reges terræ,
quia audierunt omnia verba oris tui.
   ⁵ Et cantent in viis Domini,
quoniam magna est gloria Domini ;
   ⁶ quoniam excelsus Dominus, et humilia respicit,
et alta a longe cognoscit.
   ⁷ Si ambulavero in medio tribulationis, vivificabis me ;
et super iram inimicorum meorum extendisti manum tuam,
et salvum me fecit dextera tua.
   ⁸ Dominus retribuet pro me.
Domine, misericordia tua in sæculum ;
opera manuum tuarum ne despicias.]
