Judges 6-9
"The people who are with you are too many for Me to give Midian into their hands ..." (7:2). Gideon's first army was too big. Finally convinced of God's presence, Gideon had gathered a huge army. But God did not want them to think, "My own power has delivered me" (v2). So the army was reduced to 300 men, and with torches and trumpets they defeated Midian. God wanted Israel, surrounded by idol-worshipers and without a king, to trust Him as Defender.
God "has chosen the weak things of the world to shame the strong" (I Cor 1:27).
