Ben Sira 27:14-24

14 The talk of him that sweareth much maketh the hair stand upright; and their brawls make one stop his ears.
15 The strife of the proud is bloodshedding, and their revilings are grievous to the ear.
16 Whoso discovereth secrets loseth his credit; and shall never find friend to his mind.
17 Love thy friend, and be faithful unto him: but if thou betrayest his secrets, follow no more after him.
18 For as a man hath destroyed his enemy; so hast thou lost the love of thy neighbour.
19 As one that letteth a bird go out of his hand, so hast thou let thy neighbour go, and shalt not get him again
20 Follow after him no more, for he is too far off; he is as a roe escaped out of the snare.
21 As for a wound, it may be bound up; and after reviling there may be reconcilement: but he that betrayeth secrets is without hope.
22 He that winketh with the eyes worketh evil: and he that knoweth him will depart from him.
23 When thou art present, he will speak sweetly, and will admire thy words: but at the last he will writhe his mouth, and slander thy sayings.
24 I have hated many things, but nothing like him; for the Lord will hate him.
