Tragedy hit the Slonim hasidic stream on Friday, as an eight-year-old girl from the hasidic group died of an unclear ailment.

The girl, Esther Lider, passed away on Friday at Hadassah Ein Kerem Hospital in Jerusalem.

According to Behadrei Haredim half a year ago she came down with a disease that the doctors could not identify.

Two months ago it was discovered that she was suffering a rare brain disease that does not have treatment, apparently in addition to the undefined disease.

Her family members asked the public to pray for her recovery, and rabbis gave her an additional name Ruhama in an attempt to ask for kindness from God, but in the end the eight-year-old tragically died of her disease.

The girl’s father is Rabbi Yisrael Lider, a leading figure in Slonim hasidism and the son of Rabbi Yehuda Lider who was a leader of the hassidic stream.

Esther Lider’s funeral at the Mount of Olives in Jerusalem was scheduled for 11 a.m. on Friday.
