Your life will be brighter than noonday; its darkness will be like the morning. *

*Job 11:17

[…] And they said no more; and it seemed to them as they stood upon the wall that the wind died, and the light failed, and the Sun was bleared, and all sounds in the City or in the lands about were hushed: neither wind, nor voice, nor bird-call, nor rustle of leaf, nor their own breath could be heard; the very beating of their hearts was stilled. Time halted.

And as they stood so, their hands met and clasped, though they did not know it. And still they waited for they knew not what. Then presently it seemed to them that above the ridges of the distant mountains another vast mountain of darkness rose, towering up like a wave that should engulf the world, and about it lightnings flickered; and then a tremor ran through the earth, and they felt the walls of the City quiver. A sound like a sigh went up from all the lands about them; and their hearts beat suddenly again.

[…]

And so they stood on the walls of the City of Gondor, and a great wind rose and blew, and their hair, raven and golden, streamed out mingling in the air. And the Shadow departed, and the Sun was unveiled, and light leaped forth; and the waters of Anduin shone like silver, and in all the houses of the City men sang for the joy that welled up in their hearts from what source they could not tell.

And before the Sun had fallen far from the noon out of the East there came a great Eagle flying, and he bore tidings beyond hope from the Lords of the West, crying:

Sing now, ye people of the Tower of Anor,

for the Realm of Sauron is ended for ever,

and the Dark Tower is thrown down.

Sing and rejoice, ye people of the Tower of Guard,

for your watch hath not been in vain,

and the Black Gate is broken,

and your King hath passed through,

and he is victorious.

Sing and be glad, all ye children of the West,

for your King shall come again,

and he shall dwell among you

all the days of your life.

And the Tree that was withered shall be renewed,

and he shall plant it in the high places,

and the City shall be blessed.

Sing all ye people!

And the people sang in all the ways of the City.
