This is the translation into Quenya of the Song of Parting from the Silmarillion ch. 19 ‘Of Beren and Lúthien’ p. 216:

Then being now alone and upon the threshold of the final peril he made the Song of Parting, in praise of Luthien and the lights of heaven; for he believed that he must now say farewell to both love and light. Of that song these words were part:

Farewell sweet earth and northern sky,
for ever blest, since here did lie
and here with lissom limbs did run
beneath the Moon, beneath the Sun,
Lúthien Tinúviel
more fair than mortal tongue can tell.
Though all to ruin fell the world
and were dissolved and backward hurled
unmade into the old abyss,
yet were its making good, for this —
the dusk, the dawn, the earth, the sea —
that Lúthien for a time should be.
