Ben Sira 19:11-20

11 With such a word a fool will suffer pangs like a woman in labor with a child.

12 Like an arrow stuck in the flesh of the thigh, so is a word inside a fool.

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.

20 All wisdom is the fear of the Lord, and in all wisdom there is the fulfilment of the law.
