Matthew 21:42 (KJV) - "Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvelous in our eyes?"

This verse is part of a larger passage in the Gospel of Matthew that recounts Jesus' entry into Jerusalem on Palm Sunday, where he is hailed as the Messiah and Son of David by the crowds. It is a pivotal moment in the narrative of Jesus' life, as it marks the beginning of a chain of events that will ultimately lead to his crucifixion and resurrection.

In this particular verse, Jesus is addressing the chief priests and Pharisees, who have questioned his authority and challenged his teachings. He responds by referencing a passage from the Hebrew scriptures, specifically Psalm 118:22-23, which reads, "The stone which the builders refused is become the head stone of the corner. This is the Lord's doing; it is marvelous in our eyes." By quoting this verse, Jesus is asserting his own authority as the rejected cornerstone that will ultimately become the foundation of the new covenant and the cornerstone of the Christian faith.

The themes present in this verse are manifold and rich in symbolism. One of the primary themes is the concept of rejection and redemption. The imagery of the rejected stone becoming the cornerstone is a powerful metaphor for Jesus' own rejection by the religious authorities and his ultimate exaltation by God. This theme is repeated throughout the Gospels, as Jesus is repeatedly rejected by the religious establishment and the people of Israel, only to be vindicated by his resurrection and his subsequent exaltation as the head of the church.

Another important theme is that of the fulfillment of prophecy. By quoting from the Hebrew scriptures, Jesus is demonstrating that his own ministry and identity are rooted in the prophetic tradition of Israel. He is not only the fulfillment of the Messianic prophecies, but also the embodiment of the new covenant foretold by the prophets.

The context of this verse is also significant. Jesus is speaking to the chief priests and Pharisees in the temple, the very heart of Jewish religious and cultural life. By challenging their authority and citing the scriptures to bolster his own claims, Jesus is asserting a radical reinterpretation of Jewish identity and faith. He is arguing that the religious establishment has failed to recognize the true cornerstone of their faith, and that their rejection of him will ultimately lead to their own downfall.

In addition, the symbolism of the cornerstone itself is crucial to understanding the deeper meaning of this verse. In ancient architecture, the cornerstone was the first stone laid in a structure, and it was essential for ensuring the stability and integrity of the entire building. In this context, Jesus is presenting himself as the cornerstone of the new spiritual edifice that God is building, the foundation upon which the church will be established.

Finally, the phrase "this is the Lord's doing, and it is marvelous in our eyes" highlights the divine sovereignty at work in Jesus' ministry and in the unfolding of God's redemptive plan. Despite the rejection and opposition he faced, Jesus affirms that his exaltation and vindication are the result of God's sovereign will and power, and that they are marvelous and awe-inspiring to those who have eyes to see and ears to hear.

In conclusion, Matthew 21:42 is a rich and multi-layered verse that encapsulates many of the central themes and motifs of the Gospel of Matthew. It speaks to the rejection and exaltation of Jesus, the fulfillment of prophecy, the challenge to religious authority, and the sovereignty of God's redemptive plan. As such, it continues to resonate with believers as a powerful testament to the identity and mission of Jesus Christ.
