Luke 2:48-50

48And when they saw him they were amazed: and his mother said to him, Child, why hast thou dealt thus with us? behold, thy father and I have sought thee distressed.

49And he said to them, Why [is it] that ye have sought me? did ye not know that I ought to be [occupied] in my Father's business?

50And they understood not the thing that he said to them.
