Now his parents went to Jerusalem every year at the feast of the
passover.
And when he was twelve years old, they went up to Jerusalem after the
custom of the feast. And when they had fulfilled the days, as they
returned, the child Jesus tarried behind in Jerusalem; and Joseph and his
mother, knew not of it. But they, supposing him to have been in the
company, went a day's journey and they sought him among their kinsfolk
and acquaintance. 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 they
understood not the saying which he spake unto them.
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 favor with God and man.
Luke ii, 41-52.
