“His golden colored hair and beard gave to his appearance a celestial aspect.”
Most people think that Jesus, being Jewish, must have had dark hair. However, its not out of the question for red hair to be found in the Middle East. In 2014, a gathering of about 200 red-haired Jews came together in Israel. King David is known to have red hair as well.
The proof comes from an actual historical letter from Pontius Pilate to Tiberius Caesar. Pontius Pilate writes:
One day I observed in the midst of a group of people a young man who was leaning against a tree, calmly addressing the multitude. I was told it was Jesus. This I could easily have suspected so great was the difference between Him and those who were listening to Him. His golden colored hair and beard gave to his appearance a celestial aspect. He appeared to be about 30 years of age. Never have I seen a sweeter or more serene countenance. What a contrast between Him and His bearers with their black beards and tawny complexions!
