What is the importance of the title "The Gift of the Magi"?

The short story "The Gift of the Magi" is about a husband and wife, Jim and Della, who each sacrifice something special to give a special gift.  At the end of the story, the narrator mentions the Magi from the Bible, who brought gifts to the baby Jesus.  The narrator notes that the Magi "invented the art of giving Christmas presents" when they gave their gifts.  It is also noted that the Magi were wise, as they were also known as the "wise men."  The narrator contrasts the wisdom of the Magi with the foolishness of Della and Jim, who "unwisely sacrificed for each other."  Despite this mention of foolishness, the narrator concludes that Jim and Della are the wisest of gift givers.  The final conclusion is that all people who give gifts are the wisest, just like the Magi.
