Sirach 19:13–17

13 Question a friend, perhaps he did not do it;

but if he did anything, so that he may do it no more.

14 Question a neighbor, perhaps he did not say it;

but if he said it, so that he may not say it again.

15 Question a friend, for often it is slander;

so do not believe everything you hear.

16 A person may make a slip without intending it.

Who has never sinned with his tongue?

17 Question your neighbor before you threaten him;

and let the law of the Most High take its course.
