Luke 2:50 (KJV)

And when they found him not, they turned back again to Jerusalem, seeking him.

And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.

And all that heard him were astonished at his understanding and answers.

And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.

And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?

And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart.

And Jesus increased in wisdom and stature, and in favour with God and man.
