Luke 2:41-45

41Now His parents went to Jerusalem every year at 1the Feast of the Passover.

42And when He became twelve, they went up there according to the custom of the Feast;

43and as they were returning, after spending the 2full number of days, the boy Jesus stayed behind in Jerusalem. But His parents were unaware of it,

44but supposed Him to be in the caravan, and went a day’s journey; and they began looking for Him among their relatives and acquaintances.

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