Interesting. His argument seems based on Paul's faulty translation of Leviticus.
Whether or not Paul's translation of Leviticus is faulty, Paul's 50 A.D. understanding of the Septuagint would be germane to the discussion of the passages in question as they pertain to the OP.
And that may indeed be the case, but do not overlook that you are talking about almost 600 years between the time Leviticus was written to the time of Paul. That's a long time for original intent to change, become misunderstood, and become ingrained.
Think of Easter. Ask anyone today what the meaning of Easter is and they will tell you it's about the resurrection of Jesus. Then ask them what bunnies and eggs have to do with the resurrection of Jesus and the vast majority will say: "Uh......I don't know." Ok so why do we have bunnies and eggs all over the place on Easter when it's a celebration of the resurrection? Well the answer I have alluded to before. Bunnies and eggs are symbols of fertility linked to the goddess Eos (earlier Isis in Egypt, later Eostre in England, etc) and at Spring Equinox there would be a massive celebration to give thanks to Eos (or whichever goddess depending on your time frame and geography) and pray for fertile crops, children, etc. Through Eos the world was being resurrected. The fields would grow food again, the rivers would thaw and flow, and there would be plenty.
So the people would color eggs and offer them to Eos as a gift and paint bunnies on things and give her offerings of rabbit, etc but it was all fertility rituals about the rebirth of the Earth. Now the Popes, with their new found power granted by Rome, weren't going to have this because it was pagan, but no matter how hard they tried the people would still celebrate the Festival of Eos. So the Church simply declared that it was not the resurrection of the Earth, it was the resurrection of Jesus. They were not giving thanks and prayer to Eos, they were giving thanks and prayer to Jesus and to God. And they backed this up by killing anyone who said that they were celebrating Eos instead of Jesus.
So when children were raised parents made damned sure they told them that they were celebrating Jesus because of they didn't they would get killed and their children would probably get killed too. Over the centuries, it stuck...the idea became ingrained into our culture that we are celebrating the resurrection of Christ instead of Spring Equinox, Eos, and the resurrection of the Earth.
Now the same stuff happened way back then. Leviticus was written but then 600 years passed between it being written and the life of Paul. During that time similar stuff happened as it did with Easter and Eos, although it was more limited to Jewish culture. The Pharisees and Sadducees gained great power and through it the ability to influence behavior according to their wishes and personal agenda. Jesus flat out flipped a royal ***** over their corruption of the word of God, their arrogance, their hypocrisy, etc if you recall.
So it's not at all inconceivable for Paul's or anyone's understanding of the Septuagint (which was a Greek translation of the original Hebrew by the way) to be seriously flawed by that time due to corruption, power, simple misunderstanding sometimes, faulty tradition ingrained over time, etc. And again, as Paul had never met Jesus there would be no way for him to verify
