Sirach 21:13

13 The knowledge of a wise man shall abound like a flood: and his counsel is like a pure fountain of life.

Sirach 21:13 In-Context

11 He that keepeth the law of the Lord getteth the understanding thereof: and the perfection of the fear of the Lord is wisdom.
12 He that is not wise will not be taught: but there is a wisdom which multiplieth bitterness.
13 The knowledge of a wise man shall abound like a flood: and his counsel is like a pure fountain of life.
14 The inner parts of a fool are like a broken vessel, and he will hold no knowledge as long as he liveth.
15 If a skilful man hear a wise word, he will commend it, and add unto it: but as soon as one of no understanding heareth it, it displeaseth him, and he casteth it behind his back.
