It is as sport to a fool to do mischief: but a man of understanding hath wisdom.
– Proverbs 10:23
The word for sport means laughter and points to enjoyment or pleasure. The word for mischief literally means a plan and the context dictates whether it is positive or negative. A fool finds delight in bringing off some evil plan. He is thoroughly pleased when his plans meet with success (Proverbs 2:14; 15:21). By contrast, the man who has understanding does not delight in making and prosecuting evil plans. He finds no joy in the follies and downfalls of others, but delights in wisdom. He recognizes the supreme value of wisdom so that he will seek and sacrifice to attain it (Proverbs 2:3-4; 23:23).
