Sure, here is an in-depth commentary on the Bible verse Matthew 18:13 from the King James Version:

"And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep, than of the ninety and nine which went not astray."

This verse is part of a larger passage in the Gospel of Matthew in which Jesus teaches his disciples about the value he places on each individual, using the analogy of a shepherd searching for a lost sheep. The verse is situated within a broader context in which Jesus is instructing his followers on the importance of humility, forgiveness, and the value of each individual in the kingdom of God.

The parable of the lost sheep is a powerful illustration of God's love and concern for every person. It reflects the theme of God's relentless pursuit of those who are lost or have strayed from the path of righteousness. In this parable, the shepherd leaves the ninety-nine sheep to search for the one that has wandered away. This emphasizes the idea that every individual is precious in the eyes of God, and he is willing to go to great lengths to bring them back into the fold.

The verse also speaks to the concept of redemption and the joy that comes when a lost soul is found. The shepherd's rejoicing over the lost sheep mirrors God's joy when a sinner repents and returns to him. This highlights the theme of God's mercy and grace, which are freely given to those who are willing to turn away from sin and seek reconciliation with their creator.

The broader context of this verse includes the preceding verses in which Jesus warns against causing others to stumble and emphasizes the need for forgiveness and reconciliation within the community of believers. This reinforces the theme of the importance of every individual and the need for mutual care and support within the body of Christ.

The symbolism in this verse is rich and profound. The shepherd represents Jesus, who is the Good Shepherd that lays down his life for his sheep (John 10:11). The lost sheep represents those who have wandered away from God, and the ninety-nine who did not go astray represent those who are already in the fold. The shepherd's relentless search for the lost sheep symbolizes God's persistent love and pursuit of those who are lost in sin.

This verse also carries a warning to those who are self-righteous and judgmental, as it reminds them of the value that God places on every individual, regardless of their current state. It challenges us to also show compassion and concern for those who are lost and to rejoice when they are found.

In conclusion, Matthew 18:13 from the King James Version of the Bible conveys a powerful message about the value of every individual in the eyes of God, the joy of redemption, and the need for humility and forgiveness within the community of believers. The parable of the lost sheep serves as a beautiful illustration of God's relentless love and pursuit of those who are lost, and it challenges us to reflect that same love and compassion in our own lives.
