§ Of the Coming of Men into the West The Silmarillion

Then a council and assembly of Men was called, and great numbers came together. And the Elf-friends answered Bereg, saying: 'Truly from the Dark King come all the evils from which we fled; but he seeks dominion over all Middle-earth, and whither now shall we turn and he will not pursue us? Unless he be vanquished here, or at least held in leaguer. Only by the valour of the Eldar is he restrained, and maybe it was for this purpose, to aid them at need, that we were brought into this land.'
