As long as we're being picky here, we don't know how many wise men there were or their names, just 3 that gifts are mentioned.

Matthew 2:1 "behold, there came wise men from the east to Jerusalem,... 2:11 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."
