The king of Ai suffers a horrible fate, he is hung on a tree. His body is hung up as an example of what happens to the “king of sinners”, how God brings justice and victory to His people. We look ahead to Jesus who was treated as the king of sinners, be became our curse (Galatians 3:13) and was hung on a tree (Acts 5:30). When we realise that we too deserve this fate only then can we can be saved!
