七十个七期（英语：Seventy Weeks）的异象记载在《希伯来圣经》的《但以理书》第9章第24-27节（第24节：“为你本国之民和你圣城，已经定了七十个七。要止住罪过，除净罪恶，赎尽罪孽，引进（或作彰显）永义，封住异象和预言，并膏至圣者（者或作至圣所）。”），是一个对犹太人和基督徒都相当重要的圣经预言。

另外，《马太福音》第18章记载，当彼得进前来问耶稣“我弟兄得罪我，我当饶恕他几次呢？到七次可以吗？”时，“耶稣说，我对你说，不是到七次，乃是到七十个七次（英语：seventy-seven times）”（《马太福音》第18章第22节）；接着，耶稣做了一个刻薄寡恩不怜恤人的恶仆逼债的比喻” （《马太福音》第18章第23-35节）。

The Prophecy of Seventy Weeks in chapter 9 of the Book of Daniel tells how a prophecy was given to Daniel by the angel Gabriel subsequent to the former's prayer that God would act on behalf of his people and city, which are respectively in exile and remain desolate within the narrative setting of this chapter. The prophecy has proved notoriously difficult for readers, despite the fact that it has been the subject of "intense exegetical activity" since the Second Temple period. For this reason scholars continue to follow Montgomery in referring to the history of this prophecy's interpretation as the "dismal swamp" of critical exegesis.
