Every year His parents traveled to Jerusalem for the Passover Festival.
When He was 12 years old, they went up according to the custom of the festival.a43
After those days were over, as they were returning, the boy Jesus stayed behind in Jerusalem, but His parentsb did not know it.
Assuming He was in the traveling party, they went a day's journey. Then they began looking for Him among their relatives and friends.
When they did not find Him, they returned to Jerusalem to search for Him.
After three days, they found Him in the temple complex sitting among the teachers, listening to them and asking them questions.
And all those who heard Him were astounded at His understanding and His answers.
When His parents saw Him, they were astonished, and His mother said to Him, "Son, why have You treated us like this? Your father and I have been anxiously searching for You."
"Why were you searching for Me?" He asked them. "Didn't you know that I had to be in My Father's house?" c50
But they did not understand what He said to them.
