Luke 20:17 → Psalms 118:22

At the climax of the Parable of the Wicked Tenants, Jesus looks directly at the leaders of Israel and asks, "Then what is the meaning of that which is written: 'The stone the builders rejected has become the cornerstone'?" — a verbatim citation of Psalm 118:22 introduced by the formal quotation formula "that which is written," marking this as a Direct Quotation. The psalm's rejection-vindication declaration becomes Jesus's own prosopological self-identification: the builders are the vinedressers of the parable (the religious authorities), and the rejected stone is the murdered son, whom God will vindicate. Luke's version drops Psalm 118:23 but immediately adds (v. 18) the falling-and-crushing stone imagery of Isaiah 8:14 and Daniel 2:34, Luke himself bundling the wider OT stone-cluster around the Psalm 118 core. The Connection Method is Promise-Fulfillment — the Hallel psalm sung at Passover scripts the very rejection Jesus is about to undergo, so his death is not the failure of his messianic claim but its predicted credential — carried within the canon-wide stone theme (Longitudinal Theme): the psalm's rejected-then-exalted stone is a proverbial image applied as prophecy, not a type-antitype correspondence, and it finds its fulfillment in the crucified and risen Christ. The telos is not a lesson in vindicated underdogs but the marvel of v. 23, "this is from the LORD": the Stone the builders threw away is the one tested, chosen, and precious foundation on which everything rests, so that to behold the rejected-yet-exalted Christ is to see the cornerstone God Himself set, marvelous in our eyes and worthy of all our trust.
