The Life and Morals of Jesus of Nazareth (the Jefferson Bible), by Thomas Jefferson, , at sacred-texts.com
At Twelve Years of Age He Accompanies his Parents to Jerusalem and Returns.
AND the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him.
2 And when he was twelve years old, they went up to Jerusalem after the custom of the feast.
3 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.
4 But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance.
5 And when they found him not, they turned back again to Jerusalem, seeking him.
6 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.
7 And all that heard him were astonished at his understanding and answers.
8 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.
9 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.
10 And Jesus increased in wisdom and stature, and in favour with God and man.
