Context: Hebrews 10:1-18 is the sustained comparison between the Levitical sacrificial system (weak, repeated, unable to perfect the worshiper) and Christ's once-for-all self-offering. Verses 11-14 form the rhetorical climax: "Every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins (v. 11). But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God (v. 12), waiting from that time until his enemies should be made a footstool for his feet (v. 13). For by a single offering he has perfected for all time those who are being sanctified (v. 14)." Verse 13 translates Psalm 110:1 directly into the argument (ἕως τεθῶσιν οἱ ἐχθροὶ αὐτοῦ ὑποπόδιον τῶν ποδῶν αὐτοῦ = LXX of Ps 110:1b verbatim) but with one crucial NT addition: the participle ἐκδεχόμενος ("waiting, awaiting, expecting"). The seated Christ is not merely positioned at the right hand; He is awaiting the completion of a subjection-process that is already underway but not yet finished. Verse 13 is therefore Hebrews' most concentrated statement of inaugurated eschatology: the session is both an accomplished act (aorist "sat down," v. 12) and an ongoing expectation (present participle "awaiting," v. 13). The single sacrifice has perfected the sanctified "for all time" (εἰς τὸ διηνεκές, v. 14); yet the visible, consummated dominion of the seated Priest-King over every enemy is something awaited. This tension is not an embarrassment to Hebrews' Christology; it is its eschatological center.

Christological Connection: In its own literary-theological context, Hebrews 10:13 teaches that Christ's finished sacrificial work (v. 12's aorist "sat down") is not identical with the finished visible subjection of His enemies; between the two stands the present age, which is the interval of waiting. Within this interval, the church drawn by that single sacrifice approaches God with confidence (v. 19ff), holds fast its confession (v. 23), and stirs one another up (v. 24), precisely because its High Priest is already seated and its eschatological vindication is certain. The verse therefore teaches a Christ whose completed atoning work has inaugurated — but not consummated — His cosmic reign. It teaches believers to live now in the light of already-finished atonement while expecting not-yet-finished enemy-subjection.
Christ's relation to Psalm 110:1 is richer in 10:13 than anywhere else in Hebrews. Where 1:13 quoted Ps 110:1 as proof of the Son's superiority to angels, 8:1 cited it to establish the session as the "main point" of the priestly argument, and 10:12 used it to contrast finished work against standing priests — here, 10:13, Hebrews lets the until clause of Ps 110:1 do its eschatological work. The "until" is not an empty delay; it is the present in which the church lives. Christ's session is therefore the hinge between inaugurated reign and consummated reign: the atoning work is over; the enemy-subjection is in progress. The escalation over the Levitical shadow is total — Levitical priests had neither finished atonement nor future consummation to wait for; Christ has both, locked together in His single seated act. Beale's synthesis of Ps 8 + Ps 110 + Dan 7 is cashed out here: Christ is the Adamic-humanity dominion-holder (Ps 8, all things under His feet — positionally achieved); the Davidic session-Lord (Ps 110:1 — seated but still "awaiting"); the Son-of-Man of universal everlasting kingdom (Dan 7 — receiving service of every nation, still being actualized).
Vos's inaugurated eschatology finds its textual crystal here. The already is real: Christ sits; atonement is complete; the sanctified are perfected "for all time" (v. 14); the Spirit is poured out (cf. Acts 2:33 in this same trajectory); the kingdom has come. The not-yet is also real: death still reigns (for the moment); rebellion still speaks; persecution still presses the church (a live issue for Hebrews' original readers); the visible knee of every enemy has not yet bowed. The participle ἐκδεχόμενος ("awaiting") describes not an anxious Christ but a patient one — secure in the certainty of the Father's promise, the seated Son waits for the footstool-completion, and His church waits with Him. This is why Hebrews immediately turns to exhortation (10:19-39): draw near, hold fast, stir up — because the High Priest who sits is the High Priest who is about to return (10:37, "in just a very little while, the coming one will come and will not delay"). Kline reads the royal-priestly grant here as a covenant-oath whose execution proceeds through the session-interval until every enemy is cut off and the kingdom-grant is consummated.
Already/not-yet: Already — Christ is enthroned; the single sacrifice is complete; the sanctified are perfected for all time; the church approaches the throne of grace with confidence; the Spirit is poured out from the right hand; angels, authorities, and powers are subjected (1 Pet 3:22); all things are positionally under His feet (Eph 1:22). Not yet — the last enemy, death, is not yet destroyed (1 Cor 15:26); the visible submission of "all peoples, nations, and languages" awaits the Parousia; the creation itself groans for its liberation (Rom 8:19-22); the footstool-consummation lies ahead.
Connection Method(s): Promise-Fulfillment (primary) — Hebrews 10:13 is the NT author's application of the "until" clause of Psalm 110:1's divine oath; the verse exists specifically to explain how Ps 110:1's already-given session and its not-yet-consummated enemy-subjection cohere. Redemptive-Historical Progression (co-primary) — the verse locates Christ's session on the timeline of salvation history, identifying the present age as the waiting-interval between the session and the consummation; this is inaugurated eschatology proper. Contrast — the broader context (vv. 11-12) contrasts standing Levitical priests with the seated Christ, and 10:13's "waiting" is the seated-Christ's eschatological posture, sharply distinguished from any standing repetition. Longitudinal Theme — Kingdom (inaugurated-but-not-consummated) runs straight through the verse; the same already/not-yet applies to Temple, Sonship, and Sabbath-Rest themes in Hebrews. Anti-default check: Typology is not the right register for 10:13 — this is the NT author's own exposition of an OT oath (Ps 110:1), so Promise-Fulfillment + Redemptive-Historical Progression are primary. Vos and Beale on inaugurated eschatology are the principal scholarly frame.
