40 And the child continued to grow and gain in strength; He continued to increase in wisdom, and the spiritual blessing of God was on Him.
41 His parents were in the habit of going to Jerusalem every year at the feast of the Passover.
42 And when He was twelve years old, they went up as usual to the feast
43 and stayed the usual time. When they returned, the boy Jesus stayed behind in Jerusalem, but His parents were not aware of it.
44 They supposed that He was somewhere in the caravan, and so they traveled a whole day before they began to make an anxious search for Him among His relatives and acquaintances.
45 As they did not find Him, they returned to Jerusalem in anxious search for Him.
46 And after three days they finally found Him in the temple sitting among the teachers, listening to them and asking them questions.
47 Now everyone who was listening to Him was showing astonishment at His intelligence and at His answers.
48 When His parents saw Him, they were utterly amazed, and yet His mother said to Him, "My child, why did you treat us so? Just see how your father and I, in agony of mind, have been searching for you!"
49 Then He said to them, "Why is it that you were searching for me? Did you not know that I must be in my Father's house?"
50 But they did not understand what He said to them.
51 So He went back to Nazareth with them and continued to obey them. But His mother continued to treasure up all these sayings in her heart.
52 Meanwhile Jesus grew constantly in wisdom and in body, and in favor with God and man.
