All that is gold does not glitter

All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.

From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.

Older version:

All that is gold does not glitter;
all that is long does not last;
All that is old does not wither;
not all that is over is past.[3]

The second quatrain was added during the following revision:

Not all that have fallen are vanquished;
a king may yet be without crown,
A blade that was broken be brandished;
and towers that were strong may fall down
