²³ To do mischief is like sport to a fool,
    but a man of understanding has wisdom.

¹² He who is void of wisdom despises his neighbor,
    but a man of understanding holds his peace.

²¹ Folly is joy to him who is destitute of wisdom,
    but a man of understanding walks uprightly.

²⁷ He who has knowledge spares his words,
    and a man of understanding is of an excellent spirit.
