According to these reports, the statement was made by Rosen and picked up by various newspapers. Rosen allegedly compared the Palestinians with the Amalekites that attacked the Israelite tribes during the time of Moses. Here is the quote attributed to Rosen:
“Annihilate the Amalekites from the beginning to the end. Kill them and wrest them from their possessions. Show them no mercy. Kill continuously, one after the other. Leave no child, plant, or tree. Kill their beasts, from camels to donkeys. . . . Amalekites will remain as long as there are Jews. In every age Amalekites will surface from other races to attack the Jews, and thus the war against them must be global.”
In this story, Rosen is qouted as saying
“Those who slaughter students poring over their Torah, those who rain Qassams down indiscriminately on men, women, old and young, babes and sucklings – those who hail the destruction of Israel and dance on the blood, are Amalek in our generation,” and therefore “only with hostility, and by conquering our humane emotions that are contrary to that, will we be victorious.”
The suggestion that the Palestinians are like the Amalekites obviously suggests that similar treatment would be justified. One would have to assume that Rabbi Rosen could not possibly intend such a genocidal meaning. However, this is occurring at a time of raw hateful statements on both sides, click here and here.
