1 By the rivers of Babylon we were seated, weeping at the memory of Zion,2 Hanging our instruments of music on the trees by the waterside.3 For there those who had taken us prisoners made request for a song; and those who had taken away all we had gave us orders to be glad, saying, Give us one of the songs of Zion.4 How may we give the Lord's song in a strange land?5 If I keep not your memory, O Jerusalem, let not my right hand keep the memory of its art.6 If I let you go out of my thoughts, and if I do not put Jerusalem before my greatest joy, let my tongue be fixed to the roof of my mouth.7 O Lord, keep in mind against the children of Edom the day of Jerusalem; how they said, Let it be uncovered, uncovered even to its base.8 O daughter of Babylon, whose fate is destruction; happy is the man who does to you what you have done to us.9 Happy is the man who takes your little ones, crushing them against the rocks.

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 terr,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 sculum ;opera manuum tuarum ne despicias.]
