This may come as a surprise to you, there have been NO, ZERO, NONE corrections to the scripture. You need to get out of whatever intense indoctrination you are slaving under and read real historical information. For example, in 1948 the Qumran/Dead Sea scrolls were discovered dating to 100 BC. The scrolls showed that we have in our hands essentially the same O.T. which the Jews used in the Holy Land before the time of Jesus.
What has happened is that every false teaching group which ever came along, such as the one you are affiliated with, has reinterpreted scripture to make it line up with their teachings.
I presented evidence written by Jews for Jews, based on Jewish historical writings. You continue to post your own assertions, assumptions, and presuppositions, with ZERO evidence. Such as your claim about "Hellenistic and Kabbalistic Jews" If this were true then the Jewish Encyclopedia would have mentioned it, either in a positive or negative way. I am not interested in whatever slander, false accusations, gossip, rumors, etc. you have been taught by your leaders. What I have repeatedly asked for, and you have failed to provide, is credible, verifiable, historical evidence.
I have addressed this more than once. While it is true that "sheol" originally meant "grave." and "gehenna" originally identified the valley of Hinnom, both came to represent the final place of eternal, unending punishment for the unrighteous, in Judaism, long before the Christian era, see citation from Jewish Encyclopedia, above. So your definitions are meaningless, no matter how many times you repeat them. You should get out of your indoctrination and do a study, for yourself, on the latter meaning of "sheol" and "gehenna."
You are only partly correct, "sheol" did originally mean "grave." and "gehenna" originally identified the valley of Hinnom, however, both came to represent the final place of eternal, unending punishment for the unrighteous in Judaism, long before the Christian era. Ignoring these historical facts makes your partial information false.
