28 years ago, on the night of Vov Cheshvan, the Rebbe received Chief Rabbi of Israel Rabbi Mordechai Eliyahu, for a rare and unique yechidus.
The yechidus took place in the library next door to 770, and lasted for over two hours. During the entire time, the Rebbe spoke to Rabbi Eliyahu in Lashon Kodesh.
After the yechidus, the Rebbe accompanied Rabbi Eliyahu outside, and remained there until his car was out of sight.
