חסידות אויף זכריה 6:2

Similarly, this is the case regarding the chariot of black and red horses of Zachariah's¹¹Zachariah 6:2 [prophecy, which refers to] times of exile, in which Malchut is vested within the seventy ministering angels¹²Zohar Bereishit 46b; Siddur Im Divrei Elokim Chayim, Shaar HaMilah 145c; Shaarei Teshuvah 74a. of Nogah of Asiyah. They too are in a state of total nullification, like a horse to its rider.
