The Chief Rabbis of Israel, Isser Yehuda Unterman and Yitzhak Nissim, together with other leading rabbis, asserted that "For generations we have warned against and refrained from entering any part of the Temple Mount." A recent study of this rabbinical ruling suggests that it was both "unprecedented" and possibly prompted by governmental pressure on the rabbis, and "brilliant" in preventing Muslim–Jewish friction on the Mount. Rabbinical consensus in the Religious Zionist stream of Orthodox Judaism continues to hold that it is forbidden for Jews to enter any part of the Temple Mount and in January 2005 a declaration was signed confirming the 1967 decision. On the eve of Shavuot in 2014, or 6th Sivan, 5774 in the Hebrew calendar, 400 Jews ascended the Temple Mount; some were photographed in prayer.
