Jesus traveled through all the towns and villages of that area, teaching in the synagogues and announcing the Good News about the Kingdom. And he healed every kind of disease and illness.–Matthew 9:35
At 12, He impressed the elders – Luke 2;46,47 “After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. Everyone who heard Him was amazed at His understanding and His answers.”
In His early 30’s Jesus had disciples. John 2:1–11 states that Jesus was at a wedding (Seudat Nissuin) in Cana with his disciples.
The song “Everywhere He went, Jesus was doing good…” strikes me as notable fact. https://youtu.be/pTM_swZeC94
