Analysis of After Many Days

I'VE always been a faithful man
An' tried to live for duty,
But the stringent mode of life
Has somewhat lost its beauty.
The story of the generous bread
He sent upon the waters,
Which after many days returns
To trusting sons and daughters,
Had oft impressed me, so I want
My soul influenced by it,
And bought a loaf of bread and sought
A stream where I could try it.
I cast my bread upon the waves
And fancied then to await it;
It had not floated far away
When a fish came up and ate it.
And if I want both fish and bread,
And surely both I'm wanting,
About the only way I see
Is for me to go fishing.
