Daniel's 70th Week is another name given to the Tribulation period by Bible eschatology students. It is derived from the "seventy weeks" prophecy in Daniel 9:24-27, which some believe the first 69 "weeks" (a "week" representing a period of seven years) were already fulfilled through Jesus Christ's first coming, and the last "week" is yet to be fulfilled. Verse 27 speaks of that last "week", which some students believe is talking about "the prince that shall come" from verse 26 (one of the names used for the Antichrist):
- Then he shall confirm a covenant with many for one week; But in the middle of the week He shall bring an end to sacrifice and offering. And on the wing of abominations shall be one who makes desolate, Even until the consummation, which is determined, Is poured out on the desolate.
Bible students sometimes call this covenant the "covenant with Hell", a term that comes from the book of Isaiah (verses 15 to 18), which is a covenant with falsehood that becomes annulled. In the context of the Left Behind books, the "covenant" is talking about the seven-year agreement that would allow the Global Community seven years of licensed use of Dr. Chaim Rosenzweig's synthetic fertilizer formula in exchange for Israel being given protection from her enemies, an agreement that would be broken 3 1/2 years later by Carpathia.
The latter part of the verse is believed to be talking about the "abomination of desolation" that would be set up, which is also mentioned in the book of Daniel and later referred to by Jesus in His Olivet Discourse.
Though not directly mentioned in the Left Behind books, it is inferred to at the signing of the seven-year agreement between the Global Community and Israel in "Tribulation Force" by what the two witnesses say: "Thus begins the last terrible week of the Lord!"
