Tafsiran Ratapan 3:28: Tze'enah Ure'enah & Rashi

“Sits alone” [3:28]. When a period of mourning come to a person, he should sit alone and should wait for the good, since the Holy One has commanded everything to the person.

Let him stay alone. Whoever was befallen by mourning and trouble should sit alone and wait for good [to come].

And wait. An expression of waiting, as in, “If they say thus to us, ‘Wait דֹּמוּ!’”²⁴I Shmuel 14:9. [in the incident dealing] with Yehonoson.

For He [God] has cast it upon him. For the Master of Decrees has put this decree upon him.²⁵Alternatively, ‘until He removes it,’ i.e., until He removes the suffering from him. (Targum)
