Parallel
1 John 2:19
Clementine Vulgate · Berean Standard Bible
Ex nobis prodierunt, sed non erant ex nobis, nam, si fuissent ex nobis, permansissent utique nobiscum : sed ut manifesti sint quoniam non sunt omnes ex nobis.
They went out from us, but they did not belong to us. For if they had belonged to us, they would have remained with us. But their departure made it clear that none of them belonged to us.
