The Cities of Refuge or The Name of Jesus: A Book for the Young by John MacDuff.
Cities of Refuge were provided in the land of Israel, as per God's instruction, as a refuge for people who accidentally caused someone to die. These people were treated as innocent and these Cities of Refuge gave them shelter from the avenger of blood as long as they lived. These are heart warming sermons and the relation of The relation of Cities of Refuge with Christ is clear and forthright.
