Judges six is a setup chapter for Judges seven. It gives us the background and calling of a man named Gideon who is the next Judge in the the cycle of rebelion-captivitity-repentance-deliverance.
Gideon has been filled with fear.
1. He is threshing in a winepress. This hides the grain.
2. He declares that his clan is the weakest and he his the weakest in his clan (v. 15)
3. He destroys the altar of Baal at night.
Gideon is a far cry from the strong leader he needs to become. And yet, God chooses him to deliver Israel. A continuing theme throughout Scripture is that God uses the weak to confound the strong.
