I'm not sure about what that verse means in the Bible, but I suspect that it ties in with the Samurai code that the Japanese people live by and which explains why there was absolutely no looting after the Japan disaster. If a Japanese citizen steals from a storekeeper, for example, he or she is shamed publicly by that action by the government and by all of the citizens. Not only he or she is shamed, though, but so are his ancestors and his descendants for seven generations!
In my understanding, we can sometimes draw upon the spiritual beliefs of other cultures to help us understand and interpret the teaching of our own Messiah Code of Conduct which is reflected in the teachings of Christ in the Bible. Perhaps if someone knows exactly where that quotation appears in the Bible, that might help us to understand the context and that in turn could shed more light on the question at hand. Now, this is only my opinion, but it sounds an awful lot like the Divine Law of Cause and Effect to me. The question might be: what is the sin being referenced here? Won't some of you Bible-totin' Christians weigh in on this members's question? Waiting on you now.
After recently studying on Japanese religions I can tell you there is no connection between the samurai code and the Bible. While we can look at the two and say they are simular, assuming there is a connection or influence is completely ridiculous. I read a book on comparative religion by a doctor who made the same such assumptions. The human brain, while quite complex, is exactly that, a human brain. Therefore humans having the same thoughts or ideas can be common and not always connected. Making these kinds of assumptions is how people become mislead or misinformed. The bible, as it states, is a diction from God and bears no influence from any other cultures, or religions.
