This question is based on the Basi Legani, which discussed the topic of seven Tzadikim who each have brought the Shekinah down from one level of heaven to another.
The text states that Moshe Rabbeinu merited the giving of the Torah because he was the seventh Tzadikim and the seventh is cherished unto G-d.
I would like to know how many Tzadikim from Moshe Rabbeinu until now merited the same "lowering of the Shekinah" down one heaven.
