Musar su Salmi 117:2

Haman said that Pharaoh's plan had been foolish, since anyone cohabiting with a Jewish woman and siring a child would be siring a Jewish child (It makes no difference whether such a child is considered a ממזר, "bastard" in Jewish law in the sense that he cannot legally marry a Jewish partner). This is the reason he determined to kill all the Jews. By doing so, he would also destroy the third pillar that keeps the universe going, i.e. that keeps its spiritual potential alive. The pillar referred to is גמילות חסדים, the performance of deeds of loving kindness. Once Israel would be wiped out no vestige of חסד love, would remain in this world. Our sages in Yevamot 79 have stated that חסד is one of the three attributes that distinguish members of the Jewish people and make them different from the Gentiles (the others being chastity and pity. The relevant verse is “כי גבר עלינו חסדו”, Psalms 117,2). All the three attributes mentioned are sub categories of חסד.
