Luke 2:43-52

and when they had fulfilled the days, as they were returning, the boy Jesus tarried behind in Jerusalem; and his parents knew it not; but supposing him to be in the company, they went a day’s journey; and they sought for him among their kinsfolk and acquaintance: and when they found him not, they returned to Jerusalem, seeking for him. And it came to pass, after three days they found him in the temple, sitting in the midst of the teachers, both hearing them, and asking them questions: and all that heard him were amazed at his understanding and his answers. And when they saw him, they were astonished; and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I sought thee sorrowing. And he said unto them, How is it that ye sought me? knew ye not that I must be in my Father’s house? And they understood not the saying which he spake unto them. And he went down with them, and came to Nazareth; and he was subject unto them: and his mother kept all these sayings in her heart. And Jesus advanced in wisdom and stature, and in favor with God and men.
