The Song of Solomon

The "lilies" that feature at various places in the bible come from such a variety of habitats (valleys, fields, gardens, among thorns) as to suggest that the biblical lily is a common representation of a wide variety of flowers. Certainly the tiger lily Lilium columbianum that lives in our garden wasn't one of them, since it originates in North America. 

Solomon was particularly fond of the lily as metaphore! Thus we read in the 1769 King James Bible:

Song of Solomon 2:16
My beloved is mine, and I am his: he feedeth among the lilies.

Song of Solomon 4:5
Thy two breasts are like two young roes that are twins, which feed among the lilies.

Song of Solomon 5:13
His cheeks are as a bed of spices, as sweet flowers: his lips like lilies, dropping sweet smelling myrrh.

Song of Solomon 6:2
My beloved is gone down into his garden, to the beds of spices, to feed in the gardens, and to gather lilies.

Song of Solomon 6:3
I am my beloved's, and my beloved is mine: he feedeth among the lilies.

Song of Solomon 7:2
Thy navel is like a round goblet, which wanteth not liquor: thy belly is like an heap of wheat set about with lilies.
