Luke 2:40-47

40And the child grew and waxed strong [in spirit], filled with wisdom, and 1God's grace was upon him.

41And his parents went yearly to Jerusalem at the feast of the passover.

42And when he was twelve years old, and they went up [to Jerusalem] according to the custom of the feast

43and had completed the days, as they returned, the boy Jesus remained behind in Jerusalem, and his parents knew not [of it];

44but, supposing him to be in the company that journeyed together, they went a day's journey, and sought him among their relations and acquaintances:

45and not having found him they returned to Jerusalem seeking him.

46And it came to pass, after three days they found him in the temple, sitting in the midst of the teachers and hearing them and asking them questions.

47And all who heard him were astonished at his understanding and answers.
