Acts 22:21 → Isaiah 49:6

In the Second Servant Song, the LORD widens the Servant's vocation beyond gathering Israel: "I will also make You a light for the nations (laggôyim), to bring My salvation to the ends of the earth" (Isa 49:6). In his temple-courtyard defense, Paul recounts the risen Christ's commission in the same terms: "Go! I will send you far away to the Gentiles (εἰς ἔθνη μακράν)" — the Servant's to-the-nations horizon and far-reaching scope, now spoken to Paul as his own marching orders. This is not an explicit citation (Paul never names Isaiah here, unlike Acts 13:46-47, where he quotes Isa 49:6 with "the Lord has commanded us, saying…"); it is the same commission deployed allusively, the explicit Pisidian-Antioch citation licensing the Servant-language to be heard in this second Jerusalem speech. The connection is Promise-Fulfillment, not a type of the person — there is no escalating type-figure here, but a prophetically promised mission being carried out: the Servant's global commission realized through Christ and extended to His emissary (cf. the ongoing Light-to-the-Nations / Gentile-inclusion theme). The telos is not merely that Paul fulfills a prophecy: it is that the very word that drove a hostile crowd to scream "Rid the earth of him" (22:22) is the word by which the light of Christ reaches the ends of the earth — so that Gentiles "far away" might see and savor the glory that the Servant carries, the saving God who would not keep His salvation to one nation but lavished it on all who were far off.
