luke 2:46 And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. - Free Bible Online

      46. hearing . . . asking--The method of question and answer was the customary form of rabbinical teaching; teacher and learner becoming by turns questioner and answerer, as may be seen from their extant works. This would give full scope for all that "astonished them in His understanding and answers." Not that He assumed the office of teaching--"His hour" for that "was not yet come," and His equipment for that was not complete; for He had yet to "increase in wisdom" as well as "stature" (Lu 2:52). In fact, the beauty of Christ's example lies very much in His never at one stage of His life anticipating the duties of another. All would be in the style and manner of a learner, "opening His mouth and panting." "His soul breaking for the longing that it had unto God's judgments at all times" (Ps 119:20), and now more than ever before, when finding Himself for the first time in His Father's house. Still there would be in His questions far more than in their answers; and if we may take the frivolous interrogatories with which they afterwards plied Him, about the woman that had seven husbands and such like, as a specimen of their present drivelling questions, perhaps we shall not greatly err, if we suppose that "the questions" which He now "asked them" in return were just the germs of those pregnant questions with which He astonished and silenced them in after years: "What think ye of Christ? Whose Son is He? If David call Him Lord, how is He then his Son?" "Which is the first and great commandment?" "Who is my neighbour?"
