While we don't know what Jesus looked like, we do know that He didn't look like the common depictions of Him with long hair. After all, this same Jesus inspired the apostle Paul to write in 1 Corinthians 11:14: t "Does not even nature itself teach you that if a man has long hair, it is a dishonor to him?"
In addition to this instruction regarding long hair on men, the Bible also contains circumstantial evidence that Jesus didn't have long hair.
Perhaps the most telling is that when Judas betrayed Jesus, he had to identify Jesus by a kiss. That was the prearranged signal Judas had given so that the guards could identify Jesus. Why did Judas have to do that? Because Jesus looked just like any average man of His day, and they wouldn't have been able to identify Him if Judas hadn't betrayed Him with a kiss.
This incident shows us that Jesus looked like any ordinary, average Jew of His day; there was nothing distinguishing about Him. The messianic prophecy of Isaiah 53:2 (NIV) says of Him: "He had no beauty or majesty to attract us to him, nothing in his appearance that we should desire him."
A Feb. 24, 2004, Associated Press article reports: "'Jesus didn't have long hair,' said physical anthropologist Joe Zias, who has studied hundreds of skeletons found in archaeological digs in Jerusalem. 'Jewish men back in antiquity did not have long hair.' 'The Jewish texts ridiculed long hair as something Roman or Greek,' said New York University's Lawrence Schiffman" ("Jesus Scholars Find Fault in Gibson's 'Passion'"). However, it wasn't at all typical among even the Greeks and Romans, as plenty of statues and coins from the time attest.
"Along with extensive writings from the period, experts also point to a frieze on Rome's Arch of Titus, erected after Jerusalem was captured in AD 70 to celebrate the victory, which shows Jewish men with short hair taken into captivity" (ibid.).
The Gospels tell us that on at least two occasions Jesus slipped away into the crowds when people were trying to kill Him (Luke 4:30; John 8:59). He was able to escape harm because He was simply an average-looking man of His day and blended in with the other people around Him.
Who wanted him to wear long hair? They made him to appear like the Roman god...Below let us compare the images of Roman God Jupiter with the depiction of Jesus by the Pagan Rome.
