Isaiah 28 contrasts unreliable human refuges with the tested and precious cornerstone that God Himself establishes in Zion.
The fulfillment passages listed here (1 Cor 3:11; Matt 16:18) illuminate the Christian application summarized as "The Sure Foundation." 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.
