And when they were come into the house, they saw the young child with Mary his mother, and fell down, and worshipped him: and when they had opened their treasures, they presented unto him gifts; gold, and frankincense, and myrrh. 

The gifts of the Magi : Gold, a gift for a king; frakincense, a gift for a spiritual leader; and myrrh, a gift for a healer.  By giving such gifts, the Magi (high priests) were recognizing Jesus as messiah.
