Alarm bells, alarm bells!!
Whenever two elders say they want to have a conversation with you on the same occasion, they have only one thing on their mind - the two witness rule!
They are looking for info from you which requires corroboration by them both.
Are JW publishers required to visit other JW publishers in pairs? Nope - just elders.
Ask each elder to visit you on their own, and see what response you get!
When I was first offered a shepherding call over two years ago, I informed the elder (very nice man) that I would not sit in a room with two elders again. He told me that he'd gladly come on his own. I said great.
I'm still waiting.
