Hebrew Key Terms:
Context: In Isaiah 43, God promises restoration from Babylonian exile, comparing it to a new exodus. In verses 20-21, He declares His purpose for Israel: "My chosen people, the people I formed for Myself, that they might declare My praise." This restates Israel's covenant purpose from Exodus 19:5-6, now renewed in exile.
OT-to-OT Development:
The canonical trajectory shows covenant purpose established (Exodus 19) → crisis of exile → purpose reaffirmed (Isaiah 43) → priestly identity renewed (Isaiah 61) → ultimate fulfillment in multiethnic church.
Connections:
Connection Method(s): Promise-Fulfillment, Typology (Direct, Forward-Looking) — Isaiah's reaffirmation of Israel's covenant purpose ("the people I formed for Myself, that they might declare My praise") is a prophetic promise fulfilled in the church's calling to "proclaim the virtues of Him who called you" (1 Pet 2:9), with Christ as the true chosen Servant.
Christological Connection: Christ is the ultimate chosen Servant (Isaiah 42:1; Matt 12:18) who perfectly declares God's praise through His obedient life, sacrificial death, and glorious resurrection. He is the true Israel who fulfills the covenant purpose. The church, united to Christ, shares in His mission to declare God's praise to the nations (Matt 28:19-20). Through the Spirit, believers are God's new creation (2 Cor 5:17), formed in Christ to display the glories of redeeming grace (Eph 2:10; 1 Pet 2:9).
