Hebrews 7:25 → Isaiah 53:12

Hebrews grounds Christ's never-ending priestly intercession — "He always lives to intercede for them" — in the final clause of the Servant Song: the Servant "made intercession for the transgressors" (53:12, LXX kai dia tas anomias autōn paredothē... kai dia tas hamartias autōn paredothē, with the MT's yapgîaʿ, "intercede"). Isaiah 53:12 pairs two priestly acts — "He bore the sin of many" (the sacrifice) and "made intercession for the transgressors" (the ongoing advocacy). Hebrews has already claimed the first for Christ (9:28, "to bear the sins of many," verbatim 53:12); here it claims the second, presenting the risen Christ's perpetual intercession as the eschatological extension of the Servant's intercession. The Servant who once bore sin now lives to plead for sinners — the same person, the same beneficiaries ("the transgressors" / "those who draw near"). The telos is assurance grounded in a living Person: salvation is "complete" (eis to panteles) not because the believer's grip is firm but because the Servant-Priest never dies and never stops interceding, so that Christ is desired as the unfailing Advocate whose living prayer secures what his death purchased.
