I always tell my kids that the 3 (or more) wise men were not at the manger. They met up with Mary, Joseph and Jesus later. But they did follow the star that shined upon the manger in the first place.
That post was meant for post #1. Sorry.
Well, scripture says they brought gifts of gold, frankincense and myrrh. I guess it makes sense that each brought his own unique gift.
So that implies three magi. Doesn’t prove it, though.
