From Matthew's Gospel account ...
Jesus was born in the town of Bethlehem in Judea, during the time when Herod was king. Soon afterward, some men who studied the stars came from the East to Jerusalem.
We are not told:-
how many there were.
what they were (definitely not kings)
how they travelled - no mention of camels
And they didn't wear silly hats ...
After putting the fear of God (literally!) into King Herod, they continued to Bethlehem.
And so they left, and on their way they saw the same star they had seen in the East. When they saw it, how happy they were, what joy was theirs! It went ahead of them until it stopped over the place where the child was. They went into the house ...
NOT to the stable/cattle shed/cave.
No one has any idea where their names (Gaspar, Melchior, Balthazar) came from or why they are depicted as being from different races. These names appear in about 650 AD - from nowhere!
... and when they saw the child with his mother Mary, they knelt down and worshipped him. They brought out their gifts of gold, frankincense, and myrrh, and presented them to him.
And when did they arrive? If Herod "at Bethl'em in his fury" ...
So Jesus was a toddler, not a baby; a child of approx 2 years of age.
But Matthew was anxious to explain the whole truth about CHRISTmas. Hence the three weird (but VERY expensive) visual aids.
