Came across this in some notes, food for thought.

How Did the Wise Men Know? or Is Astrology Valid?
Though this event is widely known by many - believers and non believers in Messiah alike -several misconceptions have arisen based on this passage. In fact, because the Scriptures tell us that the Wise Men were led to Yeshua by the appearance of a star, some Christians have actually ascribed validity to astrology. Some have even attempted to develop a doctrine of biblical astrology.
Let us first focus our attention on the issue of the star... certainly, no ordinary star. It is referred to as "his" star, the "King of the Jews" star, in a way that cannot apply to other stars, this star appears and disappears. This star moves from east to west. This star moves from north to south. This star hovers over one single house in Bethlehem, pointing out the exact location of the Messiah. It is very evident that this cannot be a literal star, as we know that any such star hovering over a single house would, in fact, destroy the entire planet.
Obviously, this star is something different, but what? The Greek word for "star" simply means "radiance" or "brilliance." With this star coming in the form of a light, we have the appearance of the Shechinah Glory - the visible manifestation of God's presence. Whenever God became visible in the Old Testament, such a manifestation was referred to as the Shechinah Glory. This manifested most often in the form of a light, fire, cloud or some combination of these three things. And, so, in Babylon appears a light, a brilliance, a radiance that may look from a distance like a star but has actions and characteristics that no star can or does. What these Wise Men actually saw was the Shechinah Glory, and they deduced that it was a signal that the King of the Jews had finally been born.
Still the issue remains, how did the Wise Men know? For this, we must look to the Old Testament. We must note first that the only passage in the Old Testament dating the Messiah's coming is found in the famous 70 weeks of Daniel 9. The Book of Daniel was written not in Israel, but in Babylon, much of it in Aramaic, the language of the Babylonian empire.
There is more. Daniel was always associated with Babylonian astrologers (Daniel 1:19-20; 1-13, 47; 4:7-9; 5:11-12). Nebuchadnezzar, not realizing that the source of Daniel's ability was not the stars of the heavens but the God of Heaven, made Daniel the head of all the astrologers of Babylon. As Daniel eventually also saved the lives of these astrologers by
interpreting Nebuchadnezzar's dream - there is little doubt that he was able to lead many of them to turn away from the worship of the stars to begin worshipping the God of Israel.
So then, a line of Babylonian astrologers spanning generations worshipped the true God, and having Daniel's prophecy, looked forward to the coming of the King of the Jews. We can conclude from the Book of Daniel, then, that Babylonian astrologers did know the time Messiah was to be born. However, Daniel says nothing about a star that would herald Messiah's birth. Again, how did the Wise Men know?
To find the answer, we must go back even earlier in the Old Testament to the prophecies of Balaam. Balaam was hired by the king of Moab to curse the Jews. He attempted to do so four times and each time God took control of his mouth so that he ended up blessing the Jews instead. In the course of these blessings, he sets forth four key Messianic prophecies. One of is found in
Numbers 24:17:
I see him, but not now; I behold him, but not nigh: There shall come forth a star out of Jacob, and a sceptre shall rise out of Israel,and shall smite through the corners of Moab, And break down all the sons of tumult.
Much to his own regret, Balaam was forced by God to prophesy of the coming of the Jewish Messiah, which he related to a "star." But this is not a literal star, because it says, "And a sceptre shall rise out of Israel." The star and the sceptre in this text are one and the same. We know this because the prophecy is in the form of Hebrew poetry, which is not based on rhythm or rhyme but on parallelism.) And the term "sceptre" is a symbol of royalty or kingship. This star that would rise out of Jacob, is himself a king.
Furthermore, Balaam's occupation was that of an astrologer. Even more significant is that he came from Pethor, a city on the banks of the Euphrates River in Babylonia (Numbers 22:5; Deuteronomy 23:4). With the Book of Daniel and the prophecy of Balaam, we have a double Babylonian connection here. Hence, the revelation of a star in relation to Messiah's birth via a Babylonian astrologer who, no doubt, passed the information down to his colleagues. Centuries later, Daniel was able to expound to the Babylonian astrologers as to the time that "the star of Jacob" would come.
How did the Wise Men know? Not by gazing at the stars through the pseudoscience of astrology, but by revelation of God as contained in the Scriptures through the prophecies of Balaam and Daniel. The story of the Wise Men gives no validity to astrology whatsoever.
