לָמָּה־זֶּ֣ה מְחִ֣יר בְּיַד־כְּסִ֑יל לִקְנ֖וֹת חָכְמָ֣ה וְלֶב־אָֽיִן׃
Cóż po pieniądzach w ręku głupca? dla zakupienia mądrości? Na to nie staje mu rozumu!
Rashi
Why is there a price in the fool’s hand to buy wisdom To learn the Torah.
Rashi
when the heart is not here In his heart, he has no intention of fulfilling it, and he learns only to gain a reputation.
