John 7
7:2. The Feast of Tabernacles was one of the three most important festivals of the Jewish year and was celebrated for eight days in Jerusalem. Jewish pilgrims from throughout the Roman and Parthian world would gather. The men would live in booths constructed on rooftops or elsewhere, commemorating God’s faithfulness to his people when they lived in booths in the wilderness (women and children were not required to live in the booths). This feast was known for its joyous celebration.
7:3–4. From the standpoint of general ancient political theory, the advice of Jesus’ brothers is correct; they may not know the specific matter of the Jerusalem authorities’ opposition. Most teachers taught in public places. Frank or open speech (v. 4) was considered virtuous, secret acts deceitful.
7:6–9. Pious Jewish men who lived as near as Galilee were supposed to go to the feast. It would be normal for Jesus to travel with his extended family (Josephus spoke of whole towns going). The issue is not that he will not go, but that he will only go “secretly” at first, so as not to hasten the appropriate time of his execution (cf. 7:6 with 2:4).
7:15. Most children in the Greco-Roman world could not afford even a primary education. But Palestinian Jewish children, except perhaps from the poorest homes (which a carpenter’s family was not), would learn how to read and recite the Bible, whether or not they could write. The issue here is not that Jesus is illiterate (he is not), but that he has never formally studied Scripture with an advanced teacher, yet he expounds as well as any of the scholars without citing earlier scholars’ opinions.
7:16–17. Learning by doing was a standard part of Jewish education, which included imitating one’s teacher.
7:21–24. Jesus asks the crowd to reason consistently (sound and fair judgment was paramount in Jewish teaching): why is it wrong for him to heal supernaturally on the sabbath, when circumcision (which wounds) is permitted on the sabbath? A later first-century rabbi argued similarly: If circumcising on the eighth day takes precedence over the sabbath (and it does), saving a whole life also does (as was commonly agreed). Some practices at the festivals (such as killing the Passover lamb and waving the lulab, i.e., palm branch, at the Feast of Tabernacles) likewise took precedence over the sabbath.
