"Now after Jesus was born in Bethlehem of Judea in the days of Herod the king, behold, wise men from the east came to Jerusalem, saying, ‘Where is he who has been born king of the Jews? For we saw his star when it rose and have come to worship him.’"
What is a gentile?
Simply put, gentiles are not Jewish people. The Bible often refers to all the people who are not Jews as gentiles.
Throughout the Old Testament, the Bible focuses on the nation of Israel: the Jewish people. While reading the Old Testament, it could be easy to forget that God is concerned with other nations as well. He is concerned with the hearts and souls of all men, not only the Jewish people. Here, we see that the revelation of the birth of Jesus had reached faithful men who were not Jews. They traveled a great distance to come and worship him.
Jesus is not only the King of the Jews, he is the King of Kings and Saviour to all nations.
