Judges 6:10

and I said unto you, I am the Lord, your God; fear not the gods of the Amorites, the name here standing for the Canaanitish nations in general, in whose land ye dwell; but ye have not obeyed My voice. That was the explanation of their present plight. God does not suffer disobedience in His children to go unpunished. But in sending such punishment, His intention is to draw His children back to Him in true sorrow over their sins, that they plead for mercy and forgiveness.
