Question: "What does the Bible say about the three wise men (Magi)?"
Answer: We assume that there were three wise men because of the three gifts that were given: gold, incense, and myrrh (Matthew 2:11). However, the Bible does not say there were only three wise men. There could have been many more. Tradition says that there were three and that their names were Gaspar, Melchior, and Balthasar, but since the Bible does not say, we have no way of knowing whether the tradition is accurate.
It is a common misconception that the wise men visited Jesus at the stable on the night of His birth. In fact, the wise men came days, months, or possibly even years later. That is why Matthew 2:11 says the wise men visited and worshiped Jesus in a house, not at the stable.
We know that the magi were wise men from "the East," most likely Persia, or modern-day Iran. This means the wise men traveled 800 to 900 miles to see the Christ child. Most likely, the magi knew of the writings of the prophet Daniel, who in time past had been the chief of the court seers in Persia. Daniel 9:24-27 includes a prophecy which gives a timeline for the birth of the Messiah. Also, the magi may have been aware of the prophecy of Balaam (who was from the town of Pethor on the Euphrates River near Persia) in Numbers 24:17. Balaam's prophecy specifically mentions a “star coming out of Jacob.”
The wise men were guided to look for the King of the Jews by a miraculous stellar event, the "Star of Bethlehem," which they called "His star" (Matthew 2:2). They consulted with King Herod in Jerusalem concerning the birth of Christ and were directed to Bethlehem (Matthew 2:4-8). They followed God's guidance joyfully (Matthew 2:10). Their gifts for Jesus were costly, and they worshiped Him. God warned them in a dream against returning to Herod, so, in defiance of the king, they left Judea by another route (Matthew 2:12).
So, the magi were men who 1) read and believed God's Word, 2) sought Jesus, 3) recognized the worth of Christ, 4) humbled themselves to worship Jesus, and 5) obeyed God rather than man. They were truly wise men!
