In the days of King Herod, there were three magi (not kings) who came from the East. When we think of the East with respect to Jerusalem, many people in the past have portrayed these magi as the rulers of their countries. Many times they were also portrayed as Oriental and possibly from India, the truth is much different from fiction.
These three magi are also portrayed as astrologers, but they were not in the sense that we know it today. They watched the stars for signs of a King. Most, if not all, of the magi came from the area around Babylon. The school of magi which Daniel began when Israel was in captivity for 70 years is where they were from. They studied the scriptures which foretold of a coming King, One Who would be born of a virgin in Bethlehem.
Specifically, they were studying Isaiah and that is when they saw the “star” and decided it was time to go and see this King born in Bethlehem. These magi did not do magic nor were they into the occult, they were simply educated men who had been studying the prophets of Israel. It was those prophecies which brought them to Israel and then to Jerusalem and Bethlehem, looking for the One Who would be King of Kings!
The announcement went out to the shepherds that night when God put on flesh and came to be near His Creation, so that He could pay the penalty for our sins and make right what had gone wrong at the first. He was the only One Who could pay the penalty for ALL of mankind, past, present and future. All that we need to do is believe in His sacrifice and accept the grace given to us.
