Ben Sira 37:17-27

17 As a clue to changes of heart
18 four turns of fortune appear, good and evil, life and death; and it is the tongue that continually rules them.
19 A man may be shrewd and the teacher of many, and yet be unprofitable to himself.
20 A man skilled in words may be hated; he will be destitute of all food,
21 for grace was not given him by the Lord, since he is lacking in all wisdom.
22 A man may be wise to his own advantage, and the fruits of his understanding may be trustworthy on his lips.
23 A wise man will instruct his own people, and the fruits of his understanding will be trustworthy.
24 A wise man will have praise heaped upon him, and all who see him will call him happy.
25 The life of a man is numbered by days, but the days of Israel are without number.
26 He who is wise among his people will inherit confidence, and his name will live for ever.
27 My son, test your soul while you live; see what is bad for it and do not give it that.
