Luke 2:48-51King James Version (KJV)
48 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.
49 And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
50 And they understood not the saying which he spake unto them.
51 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.
