Deuteronomy: 19:1-13 Ancient Israel and Judah had cities of refuge to which perpetrators of accidental crimes could flee for their life. Russell Shelton shows how the principle and purpose of these cities relate to God and Jesus Christ's plan of salvation for mankind. He shows even the names of the cities have significance.
