After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem and asked, “Where is the one who has been born king of the Jews? We saw his star when it rose and have come to worship him.” (Matthew 2:1-2, NIV)
I can't understand how one can conclude that a single star is pointing at a specific location. Even if I draw some lines by joining some stars, I don't think I can point at a specific location on earth. Even if I think that it points to a particular place, when I reached that place, the same line will point again somewhere ahead from that location.
The wise men were from the east, indicating that they were not Jews, I presume. They simply saw an unusual star and are able to calculate or know that a new king of the Jews is born in Israel. From the appearance of the star, I believe it is possible to conclude that a new king is born, provided the observer truly believe in star signs. However, I still can't understand how the star provided some clue where the new born king is. Moreover, the wise men were very specific when they asked king Herod. They said "Where is the one who has been born king of the Jews?".
Why did the wise men stop at Jerusalem and asked "Where is the king of the Jews"? They could have gone up to Egypt or Greece, or even further. From their question, it sounds like they were searching in Israel only. It appears as though they knew that the king was born in Israel and hence they went straight to Jerusalem, the city of the king of Israel.
How did the Magi know the country where the new king was born by simply looking at a distant star in the sky?
