Jesus Corrected Doctrine

When Jesus was correcting scriptures, he was correcting the Septuagint which were the scriptures translated in Greek. This is why when Jesus asked the disciples will they leave him also and the disciples said where shall we go, you have the words of life. Jesus knew what was true in the Septuagint and what was false and throughout his ministry, he clarified the truth from error, he corrected doctrine, because he knew the original writings because he was the one who spoke it to the prophets.
