The story of the wise men

After Jesus was born, wise men came to look for Him, from an area which is now in either Iran or Saudi Arabia. Although they are often called the "Three Kings", the Bible does not say how many there were, or that they were kings. Three is only a guess because they brought with them three gifts.
Gold, Frankincense and Myrrh

Gold: a gift fit for a King
Frankincense: burnt in worship of God
Myrrh: a sign of mortal human-ness - it was used to bury the dead
