I agree with all three of you. In "All your sheep and your lilies of snow" I think there's some biblical imagery from Song of Solomon:
1:7 Tell me, you whom I love, where you graze your flock and where you rest your sheep at midday.
2:1 I am a rose of Sharon, a lily of the valleys.
There's nothing about snow in Song of Solomon, but the reference could have been representing the purity described in the book.
