Because we have heard that some who went out from us have troubled you with words, unsettling your souls, saying, 'You must be circumcised and keep the Torah,' to whom we gave no mitzvah;
Thus says the LORD of Armies, Don't listen to the words of the prophets who prophesy to you: they teach you vanity; they speak a vision of their own heart, and not out of the mouth of the LORD.
Remind them of these things, charging them in the sight of the Lord, that they don't argue about words, to no profit, to the subverting of those who hear.
They went out from us, but they didn't belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us.
