'Unsettling' in the Bible

“Since we have heard that some of our number to whom we gave no instruction have disturbed you with their words, unsettling your souls,

I have confidence in you in the Lord that you will adopt no other view [contrary to mine on the matter]; but the one who is disturbing you, whoever he is, will have to bear the penalty.

O that even they would cut themselves off who are unsettling you!
