“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.”
King James Version (KJV)
2:46 After three days - The first day was spent in their journey, the second, in their return to Jerusalem: and the third, in searching for him there: they found him in the temple - In an apartment of it: sitting in the midst of the doctors - Not one word is said of his disputing with them, but only of his asking and answering questions, which was a very usual thing in these assemblies, and indeed the very end of them. And if he was, with others, at the feet of these teachers (where learners generally sat) he might be said to be in the midst of them, as they sat on benches of a semicircular form, raised above their hearers and disciples.
Lu 2:46 In the temple. Probably in one of the porches of the court of the women, where the schools of the rabbis were held, and the law regularly expounded. In the midst of the teachers.
