In memory of Rabbi Levi Yitzchok ben R' Zalman Yuda Deitsch OBM
At Mount Sinai, G-d healed everyone. The blind could see and the deaf could hear. When there will be the Resurrection of the Dead, G-d will bring each person back to life in the same condition as when he passed away. Why won't G-d bring them back to life already healthy? Because when Moshiach comes, even after the Resurrection of the Dead, there will be those who will try to deny that there had been a Resurrection. If the person passed away deaf and came to life able to hear, they would claim, "It is a different person!" For this reason, G-d will bring a person to life still deaf, and only after heal him.
