In a poignant message which HaRav Dov Lando delivered in wake of the dire situation, he said: "There is a powerful Measure of Justice, Midas HaDin, hovering over the world. We are not privy to the judgment of Hashem nor to the calculations of Heaven. The prayers we evoked on Yom Kippur were surely helpful but not conclusively. We must exert ourselves more through good deeds."
He added, "In the prayer of Nesane Tokef, we said: 'Who will live and who will die' etc. Not all of these prayers were accepted in Heaven. Hashem desires us to be forgiving to one another. Who can understand the judgments of Hashem or His means of recompense? But I did hear of an effective way to pray from HaRav Nissim Karelitz, namely, to say Tehillim 91, "Yoshev Beseiser" once or twice a day. It is a powerful segulah to be saved."
He concluded his address with the words, "The situation is severe. These goyim prepared their strategy over many years. We must strengthen ourselves in Torah study, stringent observance of the mitzvos, and in being good. We must pray and pray that Hashem help us all through His protection that no one be harmed. Surely He will save us."
