Did Jesus quote from the Septuagint?
Yes. The Septuagint was the Hebrew Old Testament translated into Greek by 70 Jewish scholars before Christ. It was the Greek that Jesus always referred to, and when He quoted the Old Testament, if not in Hebrew, He quoted from the Septuagint Greek.
Les explains that the Septuagint was the Old Testament Hebrew translated into the Greek by 70 Jewish scholars years before Christ. He puts a lot of emphasis on the Septuagint because that was the Greek Jesus always referred to. Whenever Jesus would quote from the Old Testament, if He did not quote it in the Hebrew, He would quote it from the Septuagint Greek. Les also notes that many Greek scholars put the Greek language together for our benefit. He came to this study while examining the Greek word for 'corrupt' in Ephesians, looking it up in the Septuagint.
