Proverbs 10:13-15

Young's Literal Translation

¹³ In the lips of the intelligent is wisdom found, And a rod [is] for the back of him who is lacking understanding.

¹⁴ The wise lay up knowledge, and the mouth of a fool [is] near ruin.

¹⁵ The wealth of the rich [is] his strong city, The ruin of the poor [is] their poverty.
