I posted earlier the picture of the bloom on my lily that I took yesterday.
Surprise, it is open in all it's beauty !!
One of the definitions of "treasure" is a collection of precious things. What could be more precious to find than a collection of lilies.
"Consider the lilies how they grow: they toil not, they spin not; and yet I say unto you, that Solomon in all his glory was not arrayed like one of these."
