Joshua chapter 20 is a continuation of the narrative from the previous chapter, in which God commands Joshua to set aside cities of refuge for those who have committed unintentional manslaughter. In this chapter, Joshua follows God's command and sets aside six cities of refuge, three on each side of the Jordan River.
The cities of refuge were intended to provide a safe haven for those who had committed unintentional manslaughter. The cities were to be a place of refuge for those who had killed someone unintentionally, so that they could be protected from the vengeance of the victim's family. This was a way of ensuring justice and protecting the innocent from the consequences of their actions.
The cities of refuge were also a reminder of God's mercy and grace. Even though the person had committed a crime, God was still willing to provide a place of refuge and safety. This was a reminder that God is a God of justice and mercy, and that He is willing to forgive and provide a way of escape for those who have sinned.
The cities of refuge were also a reminder of the importance of justice and mercy. The cities were a reminder that justice must be served, but that mercy must also be shown. This is a reminder that justice and mercy must go hand in hand, and that justice must be tempered with mercy.
Overall, Joshua chapter 20 is a reminder of God's justice and mercy, and of the importance of justice and mercy in our lives. It is a reminder that God is willing to forgive and provide a way of escape for those who have sinned, and that justice and mercy must go hand in hand.
