SYMPATHY

I lay in sorrow, deep distressed:
My grief a proud man heard;
His looks were cold, he gave me gold
But not a kindly word.
My sorrow passed—I paid him back
The gold he gave to me;
Then stood erect and spoke my thanks
And blessed his Charity.
I lay in want, in grief and pahi:
A poor man passed my way;
He bound my head he gave me bread
He watched me night and day
How shall I pay him back again,
For all he did to me
Oh, gold is great, but greater far
Is heavenly Sympathy!
