Dating the book of judges
Because the Israelites failed to remove wicked influences from the promised land, they became entangled in sin and were conquered and afflicted by their enemies.
After the Israelites cried unto the Lord for help, He sent judges to deliver them from their enemies.
The period of the Judges comprises that time between the Conquest of Canaan and Saul, Israel's first king, approximately the period between 12 BC, the close of the Late Bronze Age.
Primary weapons of the time tended to be made of bronze, but iron weapons were beginning to appear.
The 12 heroes of the book, both male and female, seem larger than life at times, but they were imperfect, just like us. Judges takes place in ancient Canaan, the Promised Land given by God to the Jews.
Judges is a stern reminder that God punishes sin but is always ready to take the repentant back into his heart. Under Joshua, the Jews conquered the land with God's help, but after Joshua's death, the lack of a strong central government led to infighting among the tribes and periodic oppression by the wicked people who lived there.
Besides the short narrative of the book of Ruth, Judges provides the only biblical account of this time period.
