Sirach 19:14-17 Catholic Public Domain Version (CPDV)

14. Correct your neighbor, for perhaps he did not say it. But if he did say it, correct him, so that he may not say it again.

15. Correct your friend. For often a fault has been committed.

16. And do not believe every word. There is one who slips with his word, but not with his heart.

17. For who is there who has not offended with his words? Correct your neighbor before you reprimand him.
