Every year on Yom Kippur I think back on the tragic events of 1973. On October 6, the rabbinical day of Yom Kippur that year, Israel was invaded by Egypt and Syria. Israeli forces had been massed on the borders for weeks awaiting an Arab attack, but many soldiers went home to observe the fast and the army was caught off guard. More Israeli boys died on that first day of the war than on any other day in the history of modern Israel. Egyptian forces quickly overcame the Bar Lev line on the east bank of the Suez Canal and Syrian forces wiped out the cream of the Israeli tank forces in the Golan Heights. The Israeli counter-attack did not begin until October 8, the biblical date of Yom Kippur based on the sighting of the new moon. On that day, Israel overwhelmed the navies of the Arab armies, managed to stop the Egyptian advance in Sinai, and began to push the Syrians out of the Golan Heights. It would be another 17 of fierce fighting before the war ended with Israeli forces looming on the outskirts of Cairo and Damascus, but it was on the biblical date of Yom Kippur according to the sighting of the new moon that things started to turn around in that fateful October of 1973.
One of the special things about Yom Kippur is that the high priest used to proclaim the name YHVH ten times during the Temple service. According to early rabbinical sources describing the service in the Second Temple:
"The multitudes would stand in the courtyard and when they heard the explicit name coming out of the mouth of the high priest they used to kneel and prostrate, fall on their faces, and say, 'Blessed is the glorious name of his kingdom forever.'" (Mishnah, Yoma 6:2)Today some Jews believe the name must not be spoken any more. Others continue the biblical practice of using the name. All are agreed that when the Messiah comes and restores the Temple, the high priest will once again proclaim the name in the Temple on Yom Kippur. Take a few moments this Yom Kippur to learn how to proclaim the name of our Creator in the original Hebrew as the high priest used to do in times of old. Keith Johnson has recorded a wonderful video with ten combinations of the name and accompanying titles.
Have a successful fast!
