Luke 2:48-51

And when they saw him, they were astonished; and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I sought thee sorrowing. And he said unto them, How is it that ye sought me? knew ye not that I must be in my Father’s house? And they understood not the saying which he spake unto them. And he went down with them, and came to Nazareth; and he was subject unto them: and his mother kept all these sayings in her heart.
