1 JEAN 2:19

Ils sont sortis du milieu de nous, mais ils n’étaient pas des nôtres; car s’ils eussent été des nôtres, ils seraient demeurés avec nous, mais cela est arrivé afin qu’il fût manifeste que tous ne sont pas des nôtres.

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.
