I hd never heard of this before but found it a really interesting article:
"A group of right-wing Jewish activists reenacted a religious ritual from the First Temple period at the Shiloah Spring in the east Jerusalem neighborhood of Silwan Tuesday night, with the goal of removing Prime Minister Ariel Sharon from power and instituting a Jewish monarchy.
With shofars blasting in the background, the group – led by Prof. Hillel Weiss, a well-known Temple Mount activist and a lecturer on literature at Bar-Ilan University, and Rabbi Yosef Dayan, who recently threatened to instigate a death curse against Sharon – conducted the nisuah hamayim ritual, which they said “will begin the process of removing the secular Israeli government.”
“This ceremony will lay the foundations for instituting a Jewish king, a Jewish court, and the Third Temple,” Weiss told the 40 participants sitting near the Shiloah Spring. “We will draw inspiration and strength from the ceremony as the holy priests did in Temple times, and we will ensure that the Jewish people will not be removed from their land.”
Standing next to the running water, said to also be used in Temple times to spiritually cleanse the high priest during the Yom Kippur services, Dayan blew the shofar while Weiss collected holy water.
“The purpose of the ceremony is to remove the current government, and in order to do so we need to draw strength from the pools of salvation,” Weiss said. “If we want to make a revolution, then we need to change the course of the winds blowing among the people.”
