Significance: Jesus' commissioning charge "you will be My witnesses" (esesthe mou martyres) in Acts 1:8 directly echoes Yahweh's designation of Israel as "My witnesses" ('edai) in Isa 43:10: "You are My witnesses, declares the LORD, and My servant whom I have chosen, so that you may know and believe Me and understand that I am He." In the Isaianic context, the witness-calling is bound to the 'ani hu ("I am He") divine identity declaration — Israel is constituted as a witness community precisely to testify to Yahweh's incomparable identity as Savior and Creator. Acts 1:8 transfers this calling from ethnic Israel to the apostolic community as witnesses to Jesus' resurrection, extending the geographic scope from Israel to "the ends of the earth" (cf. Isa 43:6; 49:6). The Servant of Isa 42-43 becomes the source of the witness commission rather than its object, confirming Jesus as the embodiment of the Servant who now re-delegates Israel's witness vocation to the new covenant community.
