Wisdom of Ben Sira 21:13-15

New Catholic Bible

¹³ The knowledge of a wise man increases like a flood,
    and his counsel is like a life-giving spring.
¹⁴ The mind of a fool is like a broken jar;
    it cannot retain any knowledge.
¹⁵ When an intelligent man hears words of wisdom,
    he praises them and adds to them.
When a fool hears them, he is scornful
    and casts them aside behind his back.
