"and bailiffs for your tribes": wielders of the lash, viz. (II Chronicles 19:11) "and the Levite bailiffs before you," and (Nechemiah 8:11) "and the Levites silenced all the people."
(Devarim 1:16) ("And I charged your judges at that time, saying:hear among your brothers": He told them: Be deliberate in judgment. If a (similar) case comes before you one, two, or three times, do not say: I've already ruled on this several times, but be deliberate in (the) judgment (of each case). And thus did the men of the Great Assembly say. "Be deliberate in judgment, and set up many disciples, and make a fence for the Torah.")
