How many languages did Jesus speak?

He certainly knew Hebrew. He probably knew Aramaic and used it on occasion. And He certainly knew Greek; that was the common language of the day. So those are the three that we say He knew. If He knew any other ones, we don't know, because we don't have a whole lot of information on what Jesus did in His college years, so to speak. We don't know what He did after He was 12, which is the time that children are no longer children, they become young adults and start learning, until He was 29 years old. So He may have studied Chaldean for all I know. I don't think so, but it's possible. But at least we know He knew three languages.
