Ben Sira 21:13-23

13 The perfection of the fear of God is wisdom and understanding.
14 He that is not wise in good, will not be taught.
15 But there is a wisdom that aboundeth in evil : and there is no understanding where there is bitterness.
16 The knowledge of a wise man shall abound like a flood, and his counsel continueth like a fountain of life.
17 The heart of a fool is like a broken vessel, and no wisdom at all shall it hold.
18 A man of sense will praise every wise word he shall hear, and will apply it to himself: the luxurious man hath heard it, and it shall displease him, and he will cast it behind his back.
19 The talking of a fool is like a burden in the way: but in the lips of the wise, grace shall be found.
20 The mouth of the prudent is sought after in the church, and they will think upon his words in their hearts.
21 As a house that is destroyed, so is wisdom to a fool : and the knowledge of the unwise is as words without sense.
22 Doctrine to a fool is as fetters on the feet, and like manacles on the right hand.
23 A fool lifteth up his voice in laughter: but a wise man will scarce laugh low to himself.
