Allusion4
A deliberate verbal borrowing without a citation formula.
'You were once darkness, but are now light' draws on 'the people who walked in darkness have seen a great light,' the prophetic light/darkness reversal. High coherence with Ephesians' conversion-as-illumination motif and strong verbal volume in the light/walk pairing.
High confidence'I am the light of the world... will have the light of life' draws on the people who walked in darkness seeing a great light. High Volume in the light/darkness antithesis and strong Coherence with John's prologue light theme; Isaiah's dawning light on those in the land of deep darkness is a primary source for Johannine light Christology.
High confidence'To shine on those who sit in darkness and the shadow of death' draws on Isaiah 9:2, 'the people who walked in darkness have seen a great light; those who dwelt in the land of deep darkness (shadow of death), on them has light shined.' Distinctive darkness/shadow-of-death + light combination; high volume.
High confidenceBeing delivered 'out of the power of darkness' and translated into the kingdom (v.13) draws on Isaiah's people walking in darkness who see a great light and the dawning kingdom of the messianic son (9:6-7). Light/darkness reversal plus an established kingdom of a royal son cohere tightly.

Medium confidenceLight shining on those in darkness echoes Isaiah's people who 'walked in darkness' seeing a great light, reinforcing the gospel-as-dawn imagery. Coherent with the Isaianic light theme already in play, though the verbal contact is general.
Medium confidence'Turn from darkness to light' recalls 'the people that walked in darkness have seen a great light; they that dwell in the land of the shadow of death, upon them has the light shined' — the prophetic image of light dawning on those in darkness.
Medium confidence'The people who walked in darkness have seen a great light' — the night-to-day, darkness-to-light reversal of vv.12-13 resonates with this classic salvation-light oracle.
Medium confidence'The people who walked in darkness have seen a great light' offers the light-shining-in-darkness topos. Low confidence and somewhat contested: the motif is broad and could derive from several light texts, but it coheres with the Prologue's darkness-versus-light contest.
Low confidence'The people who walked in darkness have seen a great light' supplies the light-into-darkness frame of 3:19; faint, part of the broader Isaianic light cluster.
