Have you ever heard the song “We three kings of orient are”? Well, we really don’t know for sure how many kings came to see baby Jesus. The bible never says. But it does say the kings brought three gifts. So,that is why people think there were three kings because there were three gifts. But, back in the bible times people did not have cars to cross the desert they had camels. Wise men and travelers usually traveled in large groups. That is how we know that there was more then one wise man.
You have probably seen manger scenes where Mary, Joseph, Baby Jesus, the shepherds, and the wisemen are all together. But, the wisemen actually came to see Jesus when he was around 1-2 years old not when he was a newborn. Only the shepherds came when he was a newborn.
Matthew 2:11 And when they were come into the house, they saw the young child with Mary his mother, and fell down, and worshiped him: and when they had opened their treasures, they presented unto him gifts; gold, and frankincense and myrrh.
Now, why would the wisemen present Jesus with these gifts? Why not fine jewelry, cake, or maybe a crown?
They gave him gold because Gold is the gift to honor a King. It is offered in acknowledgement that Jesus is King, Prince of Peace, Lord of Lord’s etc.
They gave him Frankincense because Frankincense is the incense burned in religious ceremonies. It is an offering to honor Jesus as God.
They gave him myrrh because Myrrh is the oil that is used to anoint a dead body before burial. It is offered as a prophecy of the way he would die.
Matthew 2: 9-10 When they had heard the king, they departed; and, lo, the star, which they saw in the east, went before them, till it came and stood over where the young child was.
10 When they saw the star, they rejoiced with exceeding great joy.
