He has swallowed up death forever! The Lord Yahweh will wipe away tears from off all faces. He will take the reproach of his people away from off all the earth, for Yahweh has spoken it.

Quotation1
A formal citation — high verbal volume, often introduced by a saying-formula.
'Death is swallowed up in victory' (v.54) quotes Isaiah's eschatological banquet oracle, 'he will swallow up death forever.' Paul follows a reading (cf. Theodotion/Aquila) giving 'in victory'; the citation formula 'then shall come to pass the word that is written' marks maximal volume. The text is the OT charter for death's defeat.
High confidenceAllusion4
A deliberate verbal borrowing without a citation formula.
"He will swallow up death forever, and the Lord GOD will wipe away tears from all faces" — direct source for "God will wipe away every tear from their eyes" (exaleipsei... pan dakryon). The eschatological consolation at the victory-banquet on the mountain. High verbal volume; recurs at Rev 21:4. Note the MT "swallow up death" vs. LXX katepien ho thanatos ischysas; John follows the tear-wiping clause closely regardless of the textual divergence in the first colon.
High confidence'He will swallow up death in victory' (LXX katepien ho thanatos ischysas) — the abolition of Death itself; source for Death being thrown into the lake of fire / the second death. Coheres with 1 Cor 15:54-55.
High confidence'He will wipe away every tear' (v.4) echoes 'the Lord GOD will wipe away tears from off all faces' and 'he will swallow up death forever' — joint source for tear-wiping and death's abolition. MT 'swallow up death' vs LXX 'death prevailed having swallowed' diverges; John follows the death-abolished sense (cf. MT / Theodotion). High volume.
High confidenceChrist 'who abolished death' echoes the eschatological promise that the LORD 'will swallow up death forever.' The abolition-of-death motif is the climactic Isaianic hope now realized in the Savior's appearing.
Medium confidenceEcho1
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
'He will swallow up death forever' — broader curse-removal / no-more-tears matrix behind 'no more curse'; faint here, stronger at Rev 21:4.
