Luke 2:39-52

39And when they had performed all things according to the law of the Lord, they returned into Galilee, to their own city Nazareth. 40And the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him. 41Now his parents went to Jerusalem every year at the feast of the passover. 42And when he was twelve years old, they went up to Jerusalem after the custom of the feast. 43And 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. 44But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance. 45And when they found him not, they turned back again to Jerusalem, seeking him. 46And 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. 47And all that heard him were astonished at his understanding and answers. 48And 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. 49And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business? 50And they understood not the saying which he spake unto them. 51And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart. 52And Jesus increased in wisdom and stature, and in favour with God and man.
