John Gill Commentary Acts 19:7

"And they were in all about twelve men." — Acts 19:7 (ASV)

And all the men were about twelve .
] The Syriac, Arabic, and Ethiopic versions, have not the word "about"; but affirm, that the men were twelve; and indeed the number being so small, the historian might be at a certainty about it: these seem to be the first materials of a Gospel church at Ephesus, which afterwards was very large and flourishing, and very likely were some of the elders of it.
