In June 1966, a delegation of Belzer Hasidim approached Rokeach, and urged him to accept the mantle of leadership for the Belz Hasidim. Rokeach asked them to seek the opinion of other Torah leaders, whereupon they solicited the approval of the Klausenberger Rebbe and the Gerrer Rebbe. The new Rebbe became the fifth Belzer Rabbi in Jerusalem on 28 July 1966. Standing at the gravesite of his uncle, the previous Belzer Rav, Rokeach received his first "kvitel" from the Yavrover Rav, a descendant of the Belzer and Ropshitzer Rebbes, as is customary in Belz. He has led the dynasty ever since.
