Ben Sira 37:21-31

21 A wicked word shall change the beast: out of which four manner of things arise, good and evil, life and death: and the tongue is continually the ruler of them. There is a man that is subtle and a teacher of many, and yet is unprofitable to his own soul.
22 A skilful man hath taught many, and is sweet to his own soul.
23 He that speaketh sophistically, is hateful: he shall be destitute of every thing.
24 Grace is not given him from the Lord: for he is deprived of all wisdom.
25 There is a wise man that is wise to his own soul: and the fruit of his understanding is commendable.
26 A wise man instructeth his own people, and the fruits of his understanding are faithful.
27 A wise man shall be filled with blessings, and they that see shall praise him.
28 The life of a man is in the number of his days: but the days of Israel are innumerable.
29 A wise man shall inherit honour among his people, and his name shall live for ever.
30 My son, prove thy soul in thy life: and if it be wicked, give it no power:
31 For all things are not expedient for all, and every kind pleaseth not every soul.
