Proverbs 10:13-15

World English Bible

¹³ Wisdom is found on the lips of him who has discernment,
    but a rod is for the back of him who is void of understanding.
¹⁴ Wise men lay up knowledge,
    but the mouth of the foolish is near ruin.
¹⁵ The rich man’s wealth is his strong city.
    The destruction of the poor is their poverty.
