Musar zu Rut 1:19

We find the same with respect to Na'ami. 'It is written (Ruth 1:19): "And the entire city was astir over her. And they said: 'Is this Na'ami?'" Rashi comments that all had gone out to bury the wife of Boaz, and all of them said: "See what happened to her because she left Eretz Yisrael!" Indeed, why did it happen? The truth is that it is "measure for measure." For certainly when she and her husband left Beth Lechem at the time of the famine because of [all] of the paupers who had converged [upon them for food], undoubtedly all cried out, saying: "Who will support us now in the time of the famine?" And because of this it was decreed upon her that when she returned to Beth Lechem all the city would be astir and would say: "See what happened to her!" — until she herself accepted the din upon her by saying (Ibid. 20): "Do not call me Na'ami ("sweet"), call me Mara ("bitter") for the Almighty has sorely embittered me."
