Greek King of Egypt, Ptolemy II Philadelphus, has 72 Jewish scholars translate the Five Books of Moses (as well as other books from the Tanach) into Greek.
Note: The title “The Septuagint” (a.k.a. “The LXX”) comes from the Greek number 70 (rounded–off from 72).
One wonders…if they rounded off the precise number in their own title, whether they also rounded off the translations….
