"How is it that you sought me? Did you not know that I must be in my Father's house?"

Luke 2:20-21, 40-52

At that time, the shepherds returned, glorifying and praising God
for all they had heard and seen, as it had been told them. And at the
end of eight days, when he was circumcised, he was called Jesus, the
name given by the angel before he was conceived in the womb. And the
child grew and became strong, filled with wisdom; and the favor of God
was upon him. Now his parents went to Jerusalem every year at the
feast of the Passover. And when he was twelve years old, they went up
according to custom; and when the feast was ended, as they were returning,
the boy Jesus stayed behind in Jerusalem. His parents did not know
it, but supposing him to be in the company they went a day's journey,
and they sought him among their kinsfolk and acquaintances; and when
they did not find him, they returned to Jerusalem, seeking him. After
three days, they found him in the temple, sitting among the teachers,
listening to them and asking them questions; and all who heard him were
amazed at his understanding and his answers. And when they saw him they
were astonished; and his mother said to him, "Son, why have you
treated us so? Behold, your father and I have been looking for you
anxiously." And he said to them, "How is it that you sought me? Did you not
know that I must be in my Father's house?" And they did not understand
the saying which he spoke to them. And he went down with them and
came to Nazareth, and was obedient to them; and his mother kept all
these things in her heart. And Jesus increased in wisdom and in
stature, and in favor with God and man.
