Gold, Frankincense, And Myrrh

"But Matthew says that the Magi, coming from the east, exclaimed 'For we have seen His star in the east, and are come to worship Him;' and that, having been led by the star into the house of Jacob to Emmanuel, they showed, by these gifts which they offered, who it was that was worshipped; myrrh, because it was He who should die and be buried for the mortal human met; gold, because He was a King, 'of whose kingdom is no end;' and frankincense, because He was God, who also 'was made known in Judea,' and was 'declared to those who sought Him not.'" (Irenaeus, Against Heresies, 3:9:2)
