Isaiah 49:6

'I have set you as a light for the Gentiles, that you should bring salvation to the uttermost parts of the earth' is quoted verbatim (LXX) as the Lord's commission justifying the turn to the Gentiles. Explicit Servant-Song citation; maximal volume.

'He would be first to proclaim light both to these people and to the Gentiles' draws directly on 'I will also give you for a light to the Gentiles, that you may be my salvation unto the end of the earth' — the same Servant text Paul cites programmatically at Acts 13:47.

'You will be witnesses... to the uttermost parts of the earth' closely tracks the Servant's commission to be 'a light to the nations, that you may be my salvation to the end of the earth.' Volume: the phrase 'to the end(s) of the earth' is a distinctive LXX echo (heos eschatou tes ges). Recurrence: strong — Luke cites Isa 49:6 explicitly at Acts 13:47 and alludes again, making it a structural thesis statement for the book. Thematic coherence: very high; this verse programs Acts' whole geographic movement. A leading candidate in the history of interpretation for the key to Acts.

'I will send you out far from here to the Gentiles' (v21) reprises the Servant's mandate to be 'a light to the nations, that my salvation may reach to the end of the earth.' Acts elsewhere quotes this verse for the Gentile mission; here it shapes the climactic sending. High thematic coherence and recurrence.

'The salvation of God is sent to the nations' echoes the Servant commission to be 'a light to the nations, that my salvation may reach to the end of the earth' — a programmatic Isaianic text Luke uses elsewhere; here it interprets the turn to the Gentiles immediately after the Isaiah 6 hardening oracle.

'that I might preach him among the Gentiles' enacts the Servant given 'as a light to the nations' to reach 'the end of the earth.' The Gentile-mission clause is the interpretive payoff of the womb-call allusion and coheres tightly with Paul's apostleship to the nations.

'I will give you as a light to the nations, that my salvation may reach to the end of the earth' supplies the 'of the world' scope of Jesus' claim. High Recurrence with 42:6 and strong Coherence with John's mission to gather scattered children of God.

'A light for revelation to the nations (Gentiles), and the glory of your people Israel' fuses the Servant's commission to be 'a light to the nations, that my salvation may reach to the end of the earth' with Israel's restoration. Volume and coherence are very high; this is among the clearest OT echoes in the chapter.

The Servant given 'as a light to the nations, that my salvation may reach to the end of the earth' is the programmatic text behind 'repentance and remission of sins... to all the nations.' Luke quotes Isa 49:6 explicitly at Acts 13:47 and alludes to it at Acts 1:8, making it the key prophetic warrant for the worldwide mission launched here. Volume and recurrence are high.

The Servant made 'a light to the nations/world' — direct background for 'you are the light of the world,' extending Israel's vocation to the disciples.

Paul's appointment as 'a teacher of the Gentiles' enacts the Servant's commission to be 'a light to the nations,' that salvation might reach the ends of the earth. His Gentile herald-role fulfills Isaiah's light-to-the-nations mandate.

That 'the Gentiles are fellow heirs... fellow partakers of his promise' realizes the Servant commission of Isaiah 49:6, 'I will make you a light to the nations, that my salvation may reach to the end of the earth.' Coherence is high with Pauline mission theology and the immediate Gentile-inclusion theme; volume rests on shared concept rather than wording, hence medium.

'The gospel must first be preached to all the nations' draws on the Servant's commission to be 'a light to the nations, that my salvation may reach to the end of the earth,' the Isaianic universalism behind the worldwide proclamation. The 'must' (eschatological necessity) plus the nations theme coheres with Isaiah's mission oracles.

2:19 'a light to those in darkness' also echoes Isa 49:6, 'I will make you a light to the nations, that my salvation may reach to the end of the earth' — the Servant-Israel light-to-Gentiles motif Paul invokes only to expose the teacher's failure.

The servant given 'as a light to the nations, that my salvation may reach to the end of the earth' undergirds the universal-mission mandate to all nations; Matthew's Galilee-of-the-nations theme (4:15-16) is here brought to fulfillment.

The immediate Servant-Song context that Paul draws on includes the Servant as light/salvation to the nations; faint contextual echo since Paul's apostolic role mirrors the Servant's commissioning. Volume low (not quoted), but availability and coherence with v.2's quotation support a contextual reading.

The mystery's content 'among the Gentiles' (v.27) resonates with the Servant given 'as a light to the nations' so salvation reaches the ends of the earth. The Gentile-inclusion-as-revealed-glory theme coheres with Colossians' worldwide gospel (v.6,23). Faint, contested.

'A light to the nations' resonates with 'the true light that enlightens everyone' (v.9), the universal scope of illumination. Low confidence: the universalizing of light is a shared Isaianic theme rather than a direct quotation.

The gathering of crowds from Idumaea, Tyre, Sidon and beyond the Jordan hints at the eschatological ingathering of the nations to the Servant who is a light to them. The named Gentile-adjacent regions raise coherence with Isaiah's universal scope, though the link is thematic, not verbal.

The commission to 'go into all the world, and preach the Good News to the whole creation' echoes the Servant's mandate to be a light to the nations reaching to the end of the earth. The universalizing scope coheres with Isaianic mission theology, but the appended ending offers no quotation, keeping the volume low.

The gospel 'preached in the whole world for a testimony to all the nations' before the end resonates with the Servant being given as 'a light to the nations, that my salvation may reach to the end of the earth.'

The Servant made 'salvation to the ends of the earth' / light to the nations stands behind 'the Savior of the world' confessed by Samaritans (v42), extending salvation beyond Israel. Strong Coherence with the universal-salvation theme; moderate Volume.

That Jesus would die 'not for the nation only but to gather the scattered children of God into one' echoes the Servant's commission to be 'a light to the nations' and to restore the dispersed of Israel, widening salvation beyond the nation. Moderate volume; coheres with John's universalizing of the death's scope.

God 'had opened a door of faith to the nations' (v27) realizes the Servant's mandate to be 'a light to the nations, that you may be my salvation to the end of the earth,' a programmatic Gentile-mission text in Luke-Acts (cf. Acts 13:47). Volume nil here (no verbal contact in v27); the link is the figural fulfillment of the nations' inclusion. Contested as an echo within this verse specifically.

The servant's mission to be 'a light to the nations' so that salvation reaches the ends of the earth resonates with the children's bread overflowing to a Gentile. Mark's narrative geography (Tyre, Decapolis) participates in the prophetic vision of the nations drawn in; faint figural availability.
