Actually, this is an allegory, not a metaphor. Metaphors are rarely used in the Gospels. A metaphor is a comparison of of unrelated objects and actions. An allegory is a deeper comparison to reveal a deeper or hidden relationship. The word metaphor is derived from the Latin "Metaphora", meaning carrying over. Allegory is derived from Latin "Allegoria", meaning figurative or veiled language.
Peace be to you.
