Luke 2:41-45, 48-49

Now His parents went to Jerusalem every year for the Passover Feast. [Deut 16:1-8; Ex 23:15] And when He was twelve years old, they went up to Jerusalem, according to the custom of the Feast; and as they were returning [to Nazareth], after spending the required number of days [at the Feast], the boy Jesus remained behind in Jerusalem. Now His parents did not know this, but supposed Him to be in the caravan, and traveled a day’s journey; and [then] they began searching [anxiously] for Him among their relatives and acquaintances. When they did not find Him, they went back to Jerusalem looking for Him [everywhere].

When they saw Him, they were overwhelmed; and His mother said to Him, “Son, why have You treated us like this? Listen, Your father and I have been [greatly distressed and] anxiously looking for You.” And He answered, “Why did you have to look for Me? Did you not know that I had to be in My Father’s house?”
