What does the Bible say about the role of Jesus in the temple?

In John 7:14-18, Jesus enters the temple during the Feast of Tabernacles and teaches, causing astonishment among those present. His doctrine is not self-originated but comes from God. This illustrates Jesus' role as God's messenger, fulfilling the prophecies of Old Testament scripture, including being God's servant as described in Isaiah 42:1. His teaching was significant, not only because of his divine authority but because it drew attention to the true purpose of God's commandments and their fulfillment in him.
