Isaiah 2 looks ahead to the exaltation of the LORD's rule, when the nations are drawn to His instruction and divine judgment establishes righteousness and peace.
The fulfillment passages listed here (John 4:25) illuminate the Christian application summarized as "He shall teach all nations." The correspondence is meaningful within the New Testament portrait of Jesus, but where the New Testament does not explicitly quote this exact Isaiah verse as fulfilled, it is best described as a theological or messianic correspondence rather than claiming more precision than the biblical writers themselves state.
