Because we have knowledge that some who went from us have been troubling you with their words, putting your souls in doubt; to whom we gave no such order;
This is what the Lord of armies has said: Do not give ear to the words which the prophets say to you: they give you teaching of no value: it is from themselves that their vision comes, and not out of the mouth of the Lord.
Put these things before them, giving them orders in the name of the Lord to keep themselves from fighting about words, which is of no profit, only causing error in their hearers.
They went out from us but they were not of us; if they had been of us they would still be with us: but they went out from us so that it might be made clear that they were not of us.
