Please give me the verse/verses that says Gods punishment to us is not always directly through us but sometimes through others??

God used other countries to bring about the discipline of Israel.  When they would turn from God, worship idols, and disobey him, he would allow them to go into captivity until they repented and turned back to him.  One example was when they were freed from Egypt by God.  God led them to the promised land and told them to go take it.  They grumbled and complained that there were giants in the land and so the people refused to go take the land.  When God said they would wonder in the wilderness until everyone over 20 was dead with the exception of Joshua and Caleb, they decided to go do what they were supposed to do in the first place.  Moses told them not to because God wouldn't be with them, but they did it anyway.  They were defeated, as Moses warned them they would be, by the Amalekites and Canaanites.  

There are many places where the Bible talks about punishment or discipline given through others, but I don't know of any specific verse that states what you are wanting.  The Bible (OT) also talks about the punishments given to those who commit crimes being given by the people who have the right to punish the individual(s).

I hope this helps.
