We know "the star they had seen when it rose" was seen 2 years earlier, since Herod ordered the massacre of the boys 2 years old and younger according to "the time which he had diligently enquired of the wise men." We also know the star is the one spoken of by Balaam....
"I shall see him, but not now: I shall behold him, but not nigh: there
shall come a Star out of Jacob, and a Sceptre shall rise out of
This is Balaam's 4th oracle in Numbers 24. It comes from the mouth of Balaam but is the word of the Lord as given by God.

Christ Jesus is the "light of the world."
In this most majestic event of all time, God planned and orchestrated the Star of Bethlehem to lead and display with pin-point accuracy the arrival of his only begotten with an intersection of earth's creatures centered over a manger where lay manna from heaven for a starving world:
"I have installed my king on Zion, my holy mountain." I will
proclaim the LORD's decree: He said to me, "You are my son; today I
have become your father."
(Psalm 2.6-7) God used the Star of Bethlehem to signal this day---the day Jesus was born.
