“Yet the house of Israel says, ‘The way of the Lord is not equal.' Oh house of Israel, are my ways not equal? Are your ways not unequal?”
God challenges Israel to recognise that in fact it is they whose ways are unequal and unfair. They would condemn a man for what he could do nothing about, being a ‘victim' of the behaviour of his group. God will only condemn a man for what he himself is responsible for. Of course that would include blaming him for condoning the sins of others. That was the sin of the relatives of Achan (Joshua 7:24-25). But where he had stood firm for God and His covenant, he would be guiltless.
