Luke 2:41-52 (New International Version)

The Boy Jesus at the Temple
 41Every year his parents went to Jerusalem for the Feast of the Passover. 42When he was twelve years old, they went up to the Feast, according to the custom. 43After the Feast was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it. 44Thinking he was in their company, they traveled on for a day. Then they began looking for him among their relatives and friends. 45When they did not find him, they went back to Jerusalem to look for him. 46After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. 47Everyone who heard him was amazed at his understanding and his answers. 48When 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?" 50But they did not understand what he was saying to them.

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