What does John 7:40 mean?
Once again, Jesus' preaching results in mixed reactions from the crowd. His most recent claims were tied to the concept of "living water" (John 7:37–38). In fact, Jesus made that claim during a part of the Feast of Booths specifically meant to recall God's miraculous provision of water for the nation of Israel (Exodus 17:1–7). This idea is something Jesus has brought up before (John 4:10–13; 6:35), but to some in the crowd that might have been their first time hearing it.Some of the people in Jerusalem have already come to believe in Jesus' words, mostly due to His miracles (John 7:31). Those who believe Jesus is telling the truth see Him as a fulfillment of the prophecy given in Deuteronomy 18:15, which others have suggested in the past (John 6:14). Interestingly, some see a distinction between Moses' predicted successor and the Promised One referred to as the Messiah (John 7:41).
Not everyone supports what Jesus is saying, however. As later verses will show, some people mistakenly think the Old Testament predicts Messiah in a way which Jesus does not fulfill (John 7:42; 7:52).
