Revelation 21:24-26 → Haggai 2:7

To the discouraged second-temple builders Haggai promises that after Yahweh shakes the nations, "they will come with all their treasures, and I will fill this house with glory" (Hag 2:7) — the crux phrase being חֶמְדַּת כָּל־הַגּוֹיִם (ḥemdat kol-haggôyim), the "desire / precious-things of all the nations," whose plural verb (ûbāʾû, "they shall come") gathers the wealth of the Gentiles into the glory-filled house (cf. Isa 60:5-11). Revelation 21:24-26 consummates that promise in the New Jerusalem: "the nations will walk by its light, and the kings of the earth will bring their glory into it… they will bring into it the glory and honor of the nations." This is Promise-Fulfillment carried along a Longitudinal Theme — the canon-wide motif of the eschatological in-gathering of the Gentiles' glory into God's dwelling (Hag 2:7; Isa 60; Ps 72:10-11) reaching its terminus where God and the Lamb are the temple (Rev 21:22). It is rightly an Echo rather than a direct citation: John's verbal frame here draws most closely on Isaiah 60:3 (the dominant documented allusion), with Haggai's shaking-then-treasures-into-the-house structure sounding beneath it as the parallel post-exilic source — not typology, because Haggai 2:7 is a verbal prophetic promise with its own eschatological horizon, not a historical institution standing as a type. The telos: the treasures the nations bring are not the city's wealth but its worship, and the One they come to is Himself the ḥemdat kol-haggôyim — the Desire of all nations — so that to behold this in-gathering is to see Christ as the supremely desirable end toward whom every people and king is drawn, the glory that no built house could ever contain now beheld face to face.
