43 And when they had fulfilled the days, as they returned, the child Jesus tarried behind, in Jerusalem; and Joseph and his mother knew not that he tarried;
44 But they, supposing him to have been in the company, went a day's journey; and they sought him among his kindred and acquaintance,
45 And when they found him not, they turned back again to Jerusalem, seeking him.
46 And it came to pass, after three days they found him in the temple, sitting in the midst of the doctors, and they were hearing him, and asking him questions.
47 And all who heard him were astonished at his understanding, and answers.
48 And when his parents 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, Why is it that ye sought me? Knew 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. And his mother kept all these sayings in her heart.
52 And Jesus increased in wisdom and stature, and in favor with God and man.
