They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
The 1611 reading
They went out from vs, but they were not of vs: for if they had beene of vs, they would no doubt haue continued with vs: but they went out that they might be made manifest, that they were not all of vs.
