Allusion4
A deliberate verbal borrowing without a citation formula.
'The sword of the Spirit, which is the word of God' (6:17) draws on the Servant who says God 'made my mouth like a sharp sword.' The fusion of sword + the spoken word of God is distinctive to this Servant Song; the believer wields the prophetic word as weapon.
High confidence'Out of his mouth proceeded a sharp two-edged sword' draws on the Servant's 'mouth like a sharp sword.' Strong thematic coherence (the word that judges proceeds from the mouth); John intensifies to a 'two-edged' sword, blending Isa 49:2 with Isa 11:4.
High confidence‘The word of God… sharper than any two-edged sword’ (v. 12) draws on the prophetic image of speech as a sword — the Servant's mouth ‘like a sharp sword’ in Isa 49:2. Verbal volume is the shared ‘sharp sword’ + ‘word/mouth’ collocation; Hays' criterion of thematic coherence (God's effective utterance) supports it, though Hebrews has no formula and the trope is widespread (cf. Isa 11:4; Eph 6:17; Rev 1:16).
Medium confidenceThe Christ-speaker's "sharp two-edged sword" and "the sword of my mouth" echo the Servant whose mouth is "like a sharp sword." Medium-high on volume; the word-as-weapon image is distinctive. Combines with Isa 11:4. LXX μάχαιραν ὀξεῖαν aligns with Rev ρομφαίαν ἀμφίστομον ὀξεῖαν.
