Philip found Nathanael and told him, “We have found the one about whom Moses wrote in the law, and also the prophets, Jesus son of Joseph, from Nazareth.” But Nathanael said to him, “Can anything good come from Nazareth?” Philip said to him, “Come and see.” John 1:45–46
Nathanael, who also goes by the name Bartholomew, reacted strongly to the news from his friend Philip that they had found the promised Messiah. Why did Nathanael react this way? Most likely because it was common knowledge among the Jews that the promised Messiah would come from Bethlehem, not from Nazareth. So Nathanael immediately raises this doubt because of Jesus’ supposed origin. Of course, Jesus actually was born in Bethlehem and only later moved to Nazareth, but Nathanael did not immediately realize this.
