His thoughts are with us here in Chicago.
Is it possible to have a minyan come over to lein the Aseres Hadibros at his bedside? Please try and arrange it, there are still a few hours till Yom Tov. All people were healed by Ma’amad Har Sinai, and he should also be completely healed by hearing the parsha of kabalas haTorah.
May your brother merit a complete recovery tomorrow and spend time with his wife and family before returning to the bais medrash.
