Charles Ellicott Commentary Acts 19:7

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

And all the men were about twelve.—Better, The men were in all about twelve. The whole narrative seems to imply that they were not individual cases, occurring here and there from time to time, but were living together as a kind of ascetic community, attending the meetings of the Church, yet not sharing the fullness of its life.
