Jews' battle with the Muslims

When Safiyyah(RA) was captured by the Prophet (SAW), Bilal(RA) came with her and another woman and led them past some of the slain Jews. That woman cried out, struck her face and poured dust on her face after seeing the corpses.When Prophet(SAW) saw her, he said, "Take this she-devil away from me!". What was the reason he said this to that woman? Can anyone answer please?
