Good news! Luke said that Joseph and Mary found Jesus after 3 days (καὶ ἐγένετο μετὰ ἡμέρας τρεῖς). That probably means that he was found on the 3rd day since they traveled one day out and one day back on their journey. These 3 days will play an important role in the resurrection story, because Jesus will rise from the dead after 3 days. Thus, the distress of these parents will be like the distress of the disciples of Jesus after his death. The parents of Jesus found him in the Temple (εὗρον αὐτὸν ἐν τῷ ἱερῷ), just like the women who found the empty tomb on the 3rd day. Jesus, the 12-year-old was sitting in the middle or among the Temple masters or teachers (καθεζόμενον ἐν μέσῳ τῶν διδασκάλων), experts in the Jewish religion and traditions. He was both listening to them (καὶ ἀκούοντα αὐτῶν) and asking them questions (καὶ ἐπερωτῶντα αὐτούς). Nothing had been mentioned about his prior schooling in Nazareth, if there was any. Had he been trained at the local synagogue in Nazareth?
Matthew has the discussion about the Sabbath continue in the local synagogue. This is similar to Mark, chapter 3:1-2, and Luke, chapter 6:6-7. In this synagogue, there was a man with a withered or dried out hand (καὶ ἰδοὺ ἄνθρωπος χεῖρα ἔχων ξηράν). They, the Pharisees, asked, inquired, or interrogated Jesus (καὶ ἐπηρώτησαν αὐτὸν λέγοντες) whether it was lawful to heal, cure, or serve anyone on the Sabbath (Εἰ ἔξεστιν τοῖς σάββασιν θεραπεῦσαι). They were trying to see if they could accuse or charge Jesus of breaking the Sabbath (ἵνα κατηγορήσωσιν αὐτοῦ). Jewish law allowed people to help in cases of distress on the Sabbath. Clearly, this was a trap question.
