But then you could also find references that don't support these minor shades of meaning. When you are at the level of understanding Greek that AT Robertson apparently was, you can be find shades of meaning if you need to support a preconceived narrative.What you could do is find 2-3 other occurrences of pros and see if you can sustain your argument. That is what A.T. Robertson did in the article I quoted above. FYI that is how real vs. wannabe scholars do it. That is what I would expect from someone truly interested in the truth.
This is the challenge to AT Robertson (if he were still alive) and any other scholar in any field. You can reach a level of knowledge that gives you some credibility, but then one can use that knowledge to exaggerate. This is what evolutionists, climate scientists, CDC scientists, and other highly specialized people do. This is why it is important to allow for evidence and facts that don't agree with your narrative to be accepted. Look "pros" up in Strong's or another Greek dictionary and concordance and you will see lots of ways this word is used.
