Under the Mountain dark and tall The King has come unto his hall! His foe is dead, the Worm of Dread, And ever so his foes shall fall. The sword is sharp, the spear is long, The arrow swift, the Gate is strong; The heart is bold that looks on gold; The dwarves no more shall suffer wrong. The dwarves of yore made mighty spells, While hammers fells like ringing bells In places deep, where dark things sleep, In hollow halls beneath the fells. -from The Hobbit (Dwarves Battle Song)
We have sworn, and not lightly. This oath we will keep. We are threatened with many evils, and treason not least; but one thing is not said: that we shall suffer from cowardice, from cravens or the fear of cravens. Therefore I say that we will go on, and this doom I add: the deeds that we shall do shall be the matter of song until the last days of Arda.
Of course, it is likely enough, my friends,' he said slowly, 'likely enough that we are going to our doom: the last march of the Ents. But if we stayed home and did nothing, doom would find us anyway, sooner or later. That thought has long been growing in our hearts; and that is why we are marching now. It was not a hasty resolve. Now at least the last march of the Ents may be worth a song.
