"Thorn in the flesh". What was it?

[jeremiah1five]

Paul gave his lineage. It was not of the priestly order of Aaron.

No, Saul is not a priest after the order of Aaron.

He well understood the relationship of a man and wife. He showed his experience throughout his commentary. He knew his wife better than you know a women. You can't believe the things you believe and not be failing your mate.
You're double minded in all things. You claim Saul wasn't married and then you claim he was widowed. You can't have both.

Either argument can be made from the text. I prefer to believe Saul was married and then widowed, possibly, early on.

It is very unlikely that Paul would have been widowed and he wouldn't talk about such things openly to edify the hearer. What would keep him from mention his family and estolling Timothy as "his own son in the faith" would come from losing his family to the efforts of Satan. It would be "too painful/thorn" to properly express and self serving.

The angels that sinned are 'locked up.' (2 Peter 2:4.)
