Sirach 22:16-26

16 As timber girt and bound together in a building cannot be loosed with shaking: so the heart that is stablished by advised counsel shall fear at no time.
17 A heart settled upon a thought of understanding is as a fair plaistering on the wall of a gallery.
18 Pales set on an high place will never stand against the wind: so a fearful heart in the imagination of a fool cannot stand against any fear.
19 He that pricketh the eye will make tears to fall: and he that pricketh the heart maketh it to shew her knowledge.
20 Whoso casteth a stone at the birds frayeth them away: and he that upbraideth his friend breaketh friendship.
21 Though thou drewest a sword at thy friend, yet despair not: for there may be a returning
22 If thou hast opened thy mouth against thy friend, fear not; for there may be a reconciliation: except for upbraiding, or pride, or disclosing of secrets, or a treacherous wound: for for these things every friend will depart.
23 Be faithful to thy neighbour in his poverty, that thou mayest rejoice in his prosperity: abide stedfast unto him in the time of his trouble, that thou mayest be heir with him in his heritage: for a mean estate is not always to be contemned: nor the rich that is foolish to be had in admiration.
24 As the vapour and smoke of a furnace goeth before the fire; so reviling before blood.
25 I will not be ashamed to defend a friend; neither will I hide myself from him.
26 And if any evil happen unto me by him, every one that heareth it will beware of him.
