Poetry:
The earth has grown old with its burden of care,
But at Christmas it always is young,
The heart of the jewel burns lustrous and fair,
And its soul full of music breaks the air,
When the song of angels is sung.
— Phillips Brooks (1835–1893) American Episcopal clergyman & author

Quote: Sense shines with a double luster when it is set in humility. An able yet humble man is a jewel worth a kingdom. — William Penn (1644–1718) English writer & peacemaker
