Rabbi Chaim Kanievsky, who died earlier today at home at age 94, will be buried on Sunday in his home city of Bnei Brak.
The decision to bury him on Sunday was made after consultations with top rabbis about holding his body until then. Jewish funerals in Israel usually take place within 24 hours of the death.
Police are already preparing for the funeral, which is expected to be one of the biggest ever in Israel.
Kanievsky, a hugely influential leader of the non-Hasidic Lithuanian ultra-Orthodox community in Israel, with hundreds of thousands of followers, was a scion of rabbinical dynasties known for his elite Talmud study.
