Luke 2:42-47

42And when He was twelve years old, they went up there according to the custom of the feast;

43and as they were returning, after spending the 1full number of days required, the boy Jesus stayed behind in Jerusalem, but His parents were unaware of it.

44Instead, they thought that He was somewhere in the caravan, and they went a day’s journey; and then they began looking for Him among their relatives and acquaintances.

45And when they did not find Him, they returned to Jerusalem, looking for Him.

46Then, after three days they found Him in the temple, sitting in the midst of the teachers, both listening to them and asking them questions.

47And all who heard Him 2were amazed at His understanding and His answers.
