This has been a ruse in the manuscript evidence field for a hundred years now.
Really? Philo said it was BCE. Josephus says it was BCE. The Talmud says it was BCE. Origen (whose major work on the LXX has been tragically lost) says it was BCE.
Christ himself quoted from it. Did you fail to see the post above????? Why Christ would quote from something not yet written seems a bit odd to me and makes your argument seem either silly or disingenuous.
If you don’t accept the LXX, that’s fine. At least reject it for reasons that are remotely reasonable. Even my evangelical brother who rejects the LXX would be moaning at such a ridiculous statement.
The very quotes of Christ and NT writers themselves from Septuagint verified by the copies that we have today prove its existence in the years prior to Christ's coming.
'King Ptolemy once gathered 72 Elders. He placed them in 72 chambers, each of them in a separate one, without revealing to them why they were summoned. He entered each one's room and said: 'Write for me the Torah of Moshe, your teacher.' God put it in the heart of each one to translate identically as all the others did'"
Thanks. That’s one of my pet peeves.
