Which of the wise men brought gold to baby jesus?
The identities of the wise men is not disclosed in the Bible.
The number of them is not disclosed either.
All we know is that "wise men" came and gave gold, frankincense and myrrh.
We have no good reason to suppose that there were three, or that one person only gave one gift.
However many there were, more than one could have given any of the gifts.
If there had been ten of them and three gave gold, four gave frankincense and three gave myrrh, the phrasing of the Gospel would not be wrong.
