The Prophecy of Seventy Weeks is the narrative in chapter 9 of the Book of Daniel in which Daniel prays to God to act on behalf of his people and city (Judeans and Jerusalem), and receives a detailed but cryptic prophecy of "seventy weeks" by the angel Gabriel. The prophecy has been the subject of "intense exegetical activity" since the Second Temple period.[1] James Alan Montgomery referred to the history of this prophecy's interpretation as the "dismal swamp" of critical exegesis.[2]
