Proverbs 10:13-15

Authorized (King James) Version

¹³ In the lips of him that hath understanding wisdom is found:
    but a rod is for the back of him that is void of understanding.

¹⁴ Wise men lay up knowledge:
    but the mouth of the foolish is near destruction.

¹⁵ The rich man’s wealth is his strong city:
    the destruction of the poor is their poverty.
