Proverbs 10:13-15

¹³Wisdom is found in the lips of a wise man; and a rod in the back of him that is needy of heart.

¹⁴Wise men hide knowing; but the mouth of a fool is next to confusion.

¹⁵The chattel or substance of a rich man is the city of his strength; the dread of poor men is the neediness of them.
