Commento su Ecclesiaste 7:4

The heart of the wise [will reflect on] the house of mourning. Their thoughts¹³The literal translation is somewhat difficult because the heart of the wise is located in the same place as everyone else, therefore Rashi explains that it refers to their thoughts. (Sifsei Chachomim) are [focused] on the day of death.¹⁴These are their thoughts even when they are not visiting a house of mourning. As a result they subordinate their desires and avoid sin. (Metsudas Dovid) ¹⁵Alternatively, the heart of the wise mourns over the destruction of the Beis Hamikdosh and grieve over Yisroel’s exile. (Targum)

“The heart of the wise is in a house of mourning, and the heart of fools in the house of rejoicing” (Ecclesiastes 7:4).
“The heart of the wise is in a house of mourning.” Rabbi Yitzḥak said: This is analogous to one who said to his servant: ‘Go out and bring me a fine object.’ He said to him: ‘Where do I find a fine object?’ He said to him: ‘Where you find a multitude of people going, there is a fine object.’

But the heart of the fools [are attracted] to the house of feasting. They do not fear the[ir] day of death, and their heart is as sound as a palace.¹⁶They are always thinking about joy and levity which brings a person to sin. (Metsudas Dovid) ¹⁷Alternatively, the heart of fools is involved in mockery, in eating, drinking and seeking enjoyment, and they have no concern over the suffering of their brethren. (Targum)
