Jewish boy
From the age of 12 until He began His ministry, little is known of what Jesus actually did. And so anything that we say on this subject can only be from assumption of the lives of Jewish boys and a few small sentences that refer to Jesus’ life. We know that Jesus grew up in a normal human family, and had brothers and sisters. His father was a carpenter, so as soon as He was considered to be old enough, He too entered the family business in Nazareth and became a carpenter. “Isn’t this the carpenter?” (Mark 6:3), people asked. He would no doubt have classes in Hebrew and would have heard discussions and teaching week by week at the synagogue in Nazareth where He would have gone on the Sabbath days. Nazareth was a very small village: about 35 families lived there in Jesus’ time. And it was looked down upon by most people. “Can any good thing come out of Nazareth?” (John 1:47) was a statement by Nathanael before actually meeting Jesus, but he later became a disciple of Jesus.Traveling
As a Jewish male, Jesus would have been expected to go to Jerusalem three times a year. According to the command in Deuteronomy 16:16, to celebrate the three most important festivals:- Passover and the feast of unleavened bread – March /April;
- The feast of Weeks/Pentecost – May/June;
- The feast of tabernacles — September/October.
Beginning of Jesus’ ministry
A Rabbi was considered mature, and able to teach at the age of 30. Levites began their formal service at the age of 30 (Numbers 4:2). So it is not surprising that the Son of God, the Great Teacher, the Great High Priest should begin His earthly ministry at this age.Read more in What is the Bible?
