Luke 2:41-52
41Now every year [Jesus’] parents went to Jerusalem for the festival of the Passover. 42And when he was twelve years old, they went up as usual for the festival. 43When the festival was ended and they started to return, the boy Jesus stayed behind in Jerusalem, but his parents did not know it. 44Assuming that he was in the group of travelers, they went a day’s journey. Then they started to look for him among their relatives and friends. 45When they did not find him, they returned to Jerusalem to search for him. 46After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. 47And all who heard him were amazed at his understanding and his answers. 48When his parents saw him they were astonished; and his mother said to him, “Child, why have you treated us like this? Look, your father and I have been searching for you in great anxiety.” 49He said to them, “Why were you searching for me? Did you not know that I must be in my Father’s house?” 50But they did not understand what he said to them. 51Then he went down with them and came to Nazareth, and was obedient to them. His mother treasured all these things in her heart. 52And Jesus increased in wisdom and in years, and in divine and human favor.
