Analysis of The Slave Boy's Wish

I wish I was that little bird,
Up in the bright blue sky,
That sings and flies just where he will,
And no one asks him why.
I wish I was that little brook,
That runs so swift along,
Through pretty flowers and shining stones,
Singing a merry song.
I wish I was that butterfly,
Without a thought or care,
Sporting my pretty, brilliant wings,
Like a flower in the air.
I wish I was that wild, wild deer,
I saw the other day,
Who swifter than an arrow flew,
Through the forest far away.
I wish I was that little cloud,
By the gentle south wind driven,
Floating along so free and bright,
Far, far up into heaven.
I'd rather be a cunning fox,
And hide me in a cave;
I'd rather be a savage wolf,
Than what I am-a slave.
My mother calls me her good boy,
My father calls me brave;
What wicked action have I done,
That I should be a slave?
I saw my little sister sold,
So will they do to me;
My heavenly Father, let me die,
For then I shall be free.
