Luke 2:42-52 New International Version (NIV)

⁴² When he was twelve years old, they went up to the festival, according to the custom. ⁴³ After the festival was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it. ⁴⁴ Thinking he was in their company, they traveled on for a day. Then they began looking for him among their relatives and friends. ⁴⁵ When they did not find him, they went back to Jerusalem to look for him. ⁴⁶ After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. ⁴⁷ Everyone who heard him was amazed at his understanding and his answers. ⁴⁸ When his parents saw him, they were astonished. His mother said to him, “Son, why have you treated us like this? Your father and I have been anxiously searching for you.”

⁴⁹ “Why were you searching for me?” he asked. “Didn’t you know I had to be in my Father’s house?”^{[a] 50} But they did not understand what he was saying to them.

⁵¹ Then he went down to Nazareth with them and was obedient to them. But his mother treasured all these things in her heart. ⁵² And Jesus grew in wisdom and stature, and in favor with God and man.
