As I exhorted you to stay at Ephesus when I was going into Macedonia, that you might charge certain men not to teach a different doctrine,
That thou mightest charge some - The word charge here - παραγγειλης parangeilēs - seems to mean more than is commonly implied by the word as used by us. If it had been a single direction or command, it might have been given by Paul himself before he left, but it seems rather to refer to that continuous instruction which would convince these various errorists and lead them to inculcate only the true doctrine. As they may have been numerous - as they may have embraced various forms of error, and as they might have had plausible grounds for their belief, this was evidently a work requiring time, and hence Timothy was left to effect this at leisure. It would seem that the wrath which had been excited against Paul had not affected Timothy, but that he was permitted to remain and labor without molestation. It is not certainly known who these teachers were, but they appear to have been of Jewish origin, and to have inculcated the special sentiments of the Jews respecting the law.
