Bible Discussion Thread

I am a firm believer in Jesus Christ and the fulfillment of prophecy in the Bible and all that good stories. I have read this passage of scripture this morning and I am a bit confused. If someone can explain it to make complete sense I would be more than blessed by your knowledge. From verses 19-23, it explains that an Angel of the Lord appeared to Joseph after Herod's death and told him to take to young child and his mother and go into the land of Israel, Joseph obeyed and rose up and proceeded to take the young child and his mother as the Angel had said. BUT, when he heard that Herod's son was now in Herod's position, he was AFRAID to go there NOTWITHSTANDING being forewarned of God in a dream, he TURNED ASIDE into the parts of Galilee. He lived in a city called Nazareth, which was a prophecy fulfillment in itself as it was written that Jesus would be called a Nazarene. Now my questions: 1. Was Judaea, Galilee and Nazareth all in Israel? 2. Why did Joseph become AFRAID when he heard that Archelaus was in his father's place. We know that fear is not of God. If Joseph had the Angel of the Lord appear to him in a dream and he had Baby Jesus himself in his care, why then be afraid? 3. Did Joseph disobey the Angel of God in spite of being forewarned in a dream whereby "turned aside into the parts of Galilee"? Someone would do well to explain please. I know what would make sense here but I want to see if anyone is thinking along the same lines or if maybe I am wrong. Thank You and have a blessed day in Jesus' Mighty name!
