Sirach 27:17DRA

15The speech that sweareth much shall make the hair of the head stand upright: and its irreverence shall make one stop his ears.

16Is the quarrels of the proud is the shedding of blood: and their cursing is a grievous hearing.

17He that discloseth the secret of a friend loseth his credit, and shall never find a friend to his mind.

18Love thy neighbour, and be joined to him with fidelity.

19But if thou discover his secrets, follow no more after him.
