What did the Magi (wise men) follow to find Jesus?

Answer: A star

The Magi saw His star in the east, and it went ahead of them until it stood over the place where the Child was.

“asking, “Where is the One who has been born King of the Jews? We saw His star in the east and have come to worship Him.” After they had heard the king, they went on their way, and the star they had seen in the east went ahead of them until it stood over the place where the Child was.”— Matthew 2:2, 2:9 (BSB)
