Woe to the nations of the world, who have no atonement. For Yeshayahu wrote that, instead of the copper will be gold, instead of iron -- silver, in place of wood is copper. All property destroyed by the nations will be replaced and forgiven. However, the saintly Jews who were murdered throughout our two-thousand year horror, what can replace them? Concerning this, Yoel wrote, "I will forgive them, but for the blood they spilled I can never forgive..." (Rosh Hashana 23a)
Israel is not a widow -- our God lives, and demonstrates His power through our miraculous return to Zion after two millenia of destruction. He will not forget the horrors of our past, and he will not forgive the murder of our innocent. God will not forget, and neither will we.
May the days of our mourning turn to days of exhuberance, with the completion of the universal redemption.
