"Pedigree of the Scriptures, Question 9"

The Old Testament was "complete" by 400 B.C. which means that God did not send any more new prophets from 400 B.C. until 24 A.D.  He did not speak again through prophets until John the Baptist, Jesus and the Disciples around 24 A.D., so the Septuagint was also complete; there were no new books of the Old Testament era that were in-progress, left out or missing when the Septuagint was created in 325 B.C.  Did you know these things?
