I recently looked at the fifth such prophecy, which is this:
21 He arose and took the young child and his mother, and came into the land of Israel. 22 But when he heard that Archelaus was reigning over Judea in the place of his father, Herod, he was afraid to go there. Being warned in a dream, he withdrew into the region of Galilee, 23 and came and lived in a city called Nazareth; that it might be fulfilled which was spoken through the prophets: “He will be called a Nazarene.” (World English Bible, public domain)
OK. The prophecy seems clear enough. Some one or more prophets said that someone would be called a Nazarene. The prophecy means that Jesus would live in Nazareth. But there's a problem. I discovered that there is no record of Nazareth or Nazarene, in the entire Old Testament. Here's what the public domain commentary from Jamieson, Fausset and Brown had to say about this:
John Calvin also concludes that the prophecy is that Jesus would be a Nazarite. He argues that the prophets were whoever wrote the book of Judges.
