The Raven

(Found here)

The raven is a black and craven bird,
a bird by the Law unclean.
Its carrion cry on the wind is heard ―
the raven, that black and craven bird.
Yet it is the one the Lord by His word
has sent for my keep and keen.
Oh, the raven’s a black and craven bird,
a bird by the Law unclean!
