simple writes:
It says, that the star 'WENT before' them!
And before, in the greek means, primarily this.
1. to lead forward, lead forth
Just like saying, "their hearts led them". Figurative.
You can't get a star today to do that by any contorted imaginings.
The star didn't need to "do" anything. They saw the star months before, in their homeland. If the star had been "leading" them, they wouldn't have gone to Jerusalem at all.
Herod sent them to Bethlehem, so they didn't need the star to "lead" them there, either. "Following the star" to Bethlehem is just story-telling. It serves no other purpose.
