The health of Rabbi Meir Mazuz, head of the Kisei Rahamim Yeshiva, took a downturn on Sunday night, his family said. The family added that Rabbi Mazuz is expected to undergo an additional medical treatment, which carries a risk to his life. Later, sources close to him said that the Rabbi Mazuz is sedated and on a respirator, following a worrying drop in his stats. His condition is very serious, and he is in danger of his life. As such, leading Torah sages have instructed that a name be added to Rabbi Mazuz's name, and have asked the public to pray for the complete recovery of Rabbi Refael Meir Nissim, son of Kamsana.
