Luke 2:46-52

46 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:
47 and all that heard him were amazed at his understanding and his answers.
48 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.
49 And he said unto them, How is it that ye sought me? knew ye not that I must be in my Father's house?
50 And they understood not the saying which he spake unto them.
51 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.
52 And Jesus advanced in wisdom and stature, and in favor with God and men.
