Here’s an interesting short YouTube video called:
“Were the Pyramids Built Before the Flood? (Masoretic Text vs. Original Hebrew).”
The vlogger Nathan Hoffman attempts to prove the theory that the Hebrew Masoretic text of the Old Testament was not just corrupted but intentionally tampered with. His theory makes a lot of sense. (He has another video on YouTube here too https://www.youtube.com/watch?v=FF0F8YjT1og )
Although we no longer have the original Hebrew text, the Greek Septuagint and other ancient writings line up with each other to contradict the Masoretic text. If true then geaneologies and the dating of the pyramids would be all affected.
If true, all of our modern bible translations including the NIV, ESV, NRSV (and even the King James) base the O.T. on a corrupted Masoretic text.
