The understanding of the early Christians that Jesus represented a "new covenant" (see 1 Corinthians 11:25 and Hebrews 8:6–13) is based on Jeremiah 31:31–34, in which a future Israel will repent and give God the obedience he demands.[21] The Gospel's portrayal of Jesus as a persecuted prophet owes a great deal to the account of Jeremiah's sufferings in chapters 37–44, as well as to the "Songs of the Suffering Servant" in Isaiah.[29]
