A poem about Merry just before he aids Eowyn in her battle against the Nazgul (RotK spoilers)

Reach for the sky, Meriadoc, son of Saradoc,
Mighty Prince of the Halflings.
Spread your wings and soar above the heights of your fathers.

Fangorn's draught increased your height, but only you can stand tall;
Northern kings' blade was created for this day, but what use is a knife?
Of no good, if none will wield it.
Legend's child, with legend's height and legend's sword, arise!

You come from the shadows of history and myth,
And have yourself passed through the shadows of Moria and Fangorn.
Will the child of shadows challenge the King of Shadows?
For your foe is himself a shadow, the Shadow, lord of all others that dwell in the shadow,
Save one - the Master of the One.

Yes, you are frightened; who wouldn't be?
But shall Dernhelm die unaided?

Arise.
