Jack Frost and the Hooded Crow Lyrics

Lyric discussion by offhand 

Cover art for Jack Frost and the Hooded Crow lyrics by Jethro Tull

The words begins with a poetic way of saying that Jack Frost and the hooded crow (a symbol of death in western culture) brings winter's cold and that they are cursed for it.

Yet they admonish us to be charitable because our good fate may also disappear (if the Lord finds you wanting - perhaps because of your lack of compassion) and you will only have the cold and death to share your Christmas with.

@offhand Looking up Jack Frost on Wikipedia, I chanced across Father Frost -from a Russian fairy tale that has a similar message of being kind (and of a harsh fate for those who aren't).
