לָמָּה־זֶּ֣ה מְחִ֣יר בְּיַד־כְּסִ֑יל לִקְנ֖וֹת חָכְמָ֣ה וְלֶב־אָֽיִן׃
¿De qué sirve el precio en la mano del necio para comprar sabiduría, No teniendo entendimiento?
Rashi on Proverbs
Why is there a price in the fool’s hand to buy wisdom To learn the Torah.
Rashi on Proverbs
when the heart is not here In his heart, he has no intention of fulfilling it, and he learns only to gain a reputation.
