The verse Luke 1:29 in the King James Version of the Bible reads, "And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be."

This verse is found in the first chapter of the Gospel of Luke, which is a book in the New Testament of the Bible. This particular verse is part of the story of the Annunciation, which is the angel Gabriel's visit to the Virgin Mary to tell her that she has been chosen to bear the Son of God, Jesus Christ.

In this verse, Mary's reaction to the angel's greeting is one of fear and confusion. The text says that she was "troubled at his saying," indicating that she was deeply unsettled by the angel's unexpected appearance and message. This is a natural human response to the supernatural, and it shows the depth of Mary's humility and the enormity of the task that is being asked of her.

Her response is relatable and serves to remind readers of the very human emotions that accompany extraordinary events.

The context of this verse is essential to understanding its significance. The Gospel of Luke was written by a Gentile physician named Luke, who was a companion of the apostle Paul. His gospel is the longest of the four gospels and is known for its detailed accounts of the life and teachings of Jesus Christ. The first chapter of Luke sets the stage for the rest of the gospel by introducing the miraculous events surrounding the births of John the Baptist and Jesus.

The symbolism in this verse is rich and multifaceted. The troubled reaction of Mary reflects the fear and trepidation that often accompany moments of divine revelation. It also underscores the enormity of the task that Mary is being asked to undertake. The angel's salutation to Mary carries deep significance, as it marks the beginning of the fulfillment of God's plan for the salvation of humanity through the birth of Jesus Christ. Mary's reaction serves as a reminder of the overwhelming nature of God's grace and the humility required to accept it.

In the broader context of the Bible, this verse is part of a larger narrative of God's redemptive plan for humanity. The Annunciation is a pivotal moment in salvation history, as it marks the beginning of the incarnation of Jesus Christ, who is the central figure in Christianity. Mary's response to the angel's greeting foreshadows her willingness to submit to God's will and play her part in the fulfillment of his plan.

In conclusion, Luke 1:29 captures a profound moment of divine intervention and human response that carries deep significance for the Christian faith. The troubled reaction of Mary, the themes of divine intervention and human response, and the rich symbolism all contribute to the profound impact of this verse.
