He said to them, "Why were you looking for me? Didn't you know that I must be in my Father's house?"
      5. The third day they found him in the temple, in some of the apartments belonging to the temple, where the doctors of the law kept, not their courts, but their conferences rather, or their schools for disputation; and there they found him sitting in the midst of them (Luke 2:46; Luke 2:46), not standing as a catechumen to be examined or instructed by them, for he had discovered such measures of knowledge and wisdom that they admitted him to sit among them as a fellow or member of their society. This is an instance, not only that he was filled with wisdom (Luke 2:40; Luke 2:40), but that he had both a desire to increase it and a readiness to communicate it; and herein he is an example to children and young people, who should learn of Christ to delight in the company of those they may get good by, and choose to sit in the midst of the doctors rather than in the midst of the players. Let them begin at twelve years old, and sooner, to enquire after knowledge, and to associate with those that are able to instruct them; it is a hopeful and promising presage in youth to be desirous of instruction. Many a youth at Christ's age now would have been playing with the children in the temple, but he was sitting with the doctors in the temple. (1.) He heard them. Those that would learn must be swift to hear. (2.) He asked them questions; whether, as a teacher (he had authority so to ask) or as a learner (he had humility so to ask) I know not, or whether as an associate, or joint-searcher after truth, which must be found out by mutual amicable disquisitions. (3.) He returned answers to them, which were very surprising and satisfactory, Luke 2:47; Luke 2:47. And his wisdom and understanding appeared as much in the questions he asked as in the answers he gave, so that all who heard him were astonished: they never heard one so young, no indeed any of their greatest doctors, talk sense at the rate that he did; like David, he had more understanding than all his teachers, yea, than the ancients,Psalms 119:99; Psalms 119:100. Now Christ showed forth some rays of his glory, which were presently drawn in again. He gave them a taste (says Calvin) of his divine wisdom and knowledge. Methinks this public appearance of Christ in the temple, as a teacher, was like Moses's early attempt to deliver Israel, which Stephen put this construction upon, that he supposed his brethren would have understood, by that, how God by his hand would deliver them,Acts 7:24; Acts 7:25. They might have taken the hint, and been delivered then, but they understood not; so they here might have had Christ (for aught I know) to enter upon his work now, but they were only astonished, and understood not the indication; and therefore, like Moses, he retires into obscurity again, and they hear no more of him for many years after.
