Rabbi Yosef Shalom Elyashiv has been instructed by doctors not to leave his home due to his weakening condition.
His spokesman said that “he needs mercy from Hashem,” and called on the public to pray for his recovery.
The 101-year-old Lithuanian Orthodox leader was hospitalized two weeks ago after experiencing shortness of breath, and medical tests last week revealed that Elyashiv’s heart is working at 20% capacity.
Elyashiv was diagnosed as having pulmonary edema, but his doctors determined that he did not need to remain hospitalized and that treatment and care at home would be best.
