Daniel 12:1

'Tribulation such as has not been from the beginning of creation... and never will be' closely renders Daniel 12:1, 'a time of trouble such as never has been since there was a nation till that time.' The unequaled-distress formula is distinctive and explicitly Danielic, the climactic tribulation before the deliverance of the elect.

'great oppression, such as has not been from the beginning of the world until now, no, nor ever will be' is a near-verbatim rendering of Daniel 12:1, 'a time of trouble such as never has been since there was a nation till that time'; this is the controlling source for the unequaled-tribulation clause.

Daniel's eschatological promise that 'everyone whose name is found written in the book' shall be delivered supplies the apocalyptic deliverance sense Paul gives the image. Availability in Second-Temple apocalyptic and coherence with the resurrection hope of Philippians 3 make this a strong contributor to Paul's 'book of life.'

Eschatological registry: deliverance of 'everyone who is found written in the book.' Revelation is saturated with Daniel; the heavenly book of the saved underlies the promise of 3:5. Hays: recurrence (Daniel pervades Rev) + thematic coherence.

'At that time Michael shall stand up, the great prince who stands for the children of your people' — Michael as the angelic champion/prince in the eschatological crisis. Names Michael and his protective warfare for God's people.

'Whose name has... been written' echoes Dan 12:1 'everyone who is found written in the book shall be delivered' (gegrammenos en te biblo). Eschatological register of the written/unwritten name.

‘The assembly of the firstborn who are enrolled in heaven’ (v. 23) draws on the apocalyptic book-of-life motif, classically Dan 12:1 (‘everyone found written in the book’ is delivered). Medium volume; the enrollment/registration image is the link, shared with Exod 32:32.

The eschatological deliverance of everyone found written in the book gives the names-in-heaven motif its end-time, salvific force matching Luke's contrast with mere demonic subjection. Coherence with the resurrection-life horizon supports the allusion.

The handing over to tribulation and the promise that 'he who endures to the end will be saved' echoes Daniel 12:1, where after a time of unequaled trouble 'your people shall be delivered, everyone found written in the book'; deliverance comes through, not around, the tribulation.

"there shall be a time of trouble (LXX thlipsis / Theod. hemera thlipseos) such as never has been" — the eschatological great distress that John names "the great tribulation" (tes thlipseos tes megales). Daniel supplies the technical term and the deliver-the-named-remnant frame; coherent with the sealing/deliverance arc of the whole chapter.

'A time of trouble such as never was since there was a nation.' The 'unprecedented' formula of the earthquake 'such as was not since there were men' (16:18) draws on Daniel's superlative-tribulation language.

Those 'written in the book' shall be delivered — antithesis to 'whose names have not been written in the book of life.' Hays: coherence with Daniel's book-of-deliverance at the end. LXX/Theodotion Dan 12:1.

'everyone that shall be found written in the book' delivered — the blessing on those who 'have part in the first resurrection' echoes the deliverance of the book-enrolled at the resurrection; coheres with the book-of-life motif resolved in 20:12,15.

Paul's reference to the present 'distress' and the foreshortened time may draw on Danielic expectation of a time of unparalleled distress before the end (Dan 12:1) and the apocalyptic notion of an appointed time cut short. Availability is good in a Second-Temple frame; volume is low and generic, so this is a faint contested echo.

Daniel's promise that 'your people shall be delivered, everyone found written in the book' stands behind the eschatological 'will be saved.' The deliverance of the faithful remnant through the unequaled tribulation (cited explicitly at 13:19) frames the salvation of the endurer here.

Eschatological deliverance of those 'written in the book' / sealed remnant; faint contact with the named, redeemed company. Contested as background to the sealing motif.

Beatitude/blessing formula and end-time deliverance background for 'Blessed are those invited' (Rev 19:9); faint beatitude resonance.

'Everyone whose name is written in the book' — undergirds the overcomer/inheritance contrast with the excluded (v.7-8) and the book-of-life of v.27.

'Everyone whose name shall be found written in the book' shall be delivered — parallel to the Lamb's book of life (v.27); also undergirds Rev 13:8; 20:15.

Deliverance for those 'found written in the book' — faint support for the inscribed-in/erased-from-the-city-and-life motif behind the take-away penalty. Faint.
