In Ezekiel's climactic vision the prophet sees "water flowing from under the threshold of the temple toward the east" (Ezek 47:1), a river that grows from ankle-deep to uncrossable simply by flowing from its source (47:3-5), heals the Dead Sea so that "wherever the river flows, everything will flourish" (47:9), and feeds trees whose "leaves for healing" never wither (47:12) — the eschatological sanctuary is not merely a building but the source from which life floods a dead world. This is distinct from the wilderness-rock strand (see John 7:37-39 → Exod 17:6): the source here is the temple-threshold, not the smitten rock. On "the last and greatest day of the feast" of Tabernacles — standing in the temple courts where the daily water-libation rite was enacted — Jesus cries, "If anyone is thirsty, let him come to Me and drink… 'Streams of living water will flow from within him'" (John 7:37-38), and John names the water as the Spirit (v. 39). The connection runs by Promise-Fulfillment carried along the Temple-and-Presence / Living-Water longitudinal theme — Ezekiel's temple-river vision consummated in Christ, not a historical type escalated. A visionary prophecy fails the Historicity mark of a type-vehicle (the river never flowed and the Dead Sea was never healed — a seen future is a promise, not a lived shadow God escalates), so the river-vision reaches Christ by promise-fulfillment, not by being a type. The one genuinely typological thread is the temple-institution→Christ (John 2:21, "He was speaking about the temple of His body"), kept as background: Christ takes the place the Ezekielian sanctuary-threshold held as the source-point of the life-river, the structural payoff of the Johannine Christ-as-temple Christology. The correspondence is dense (sanctuary-threshold yields a healing river to a dead land / Christ yields the indwelling Spirit to a thirsting world) and the escalation real (a river bounded by Israel's geography → the Spirit flowing from within believers themselves, who become the new temple, reaching the nations), but it is the temple-river image — not a single predictive sentence — that Jesus claims. The telos: Ezekiel's hearers longed for the day when life would pour from God's dwelling and reverse every barrenness; at Tabernacles that fountain stands up in the flesh and says come and drink, and the river now rises not in a distant valley but within the one who believes — so that to behold Christ the temple-source is to taste a satisfaction so deep and so unfailing that the thirsty soul drinks, and goes on drinking, and overflows.
