His first case was the defence of a notorious robber and murderer.
Here he occupied himself in chastening the Amalekites and other robber tribes who made raids on Judah and the Philistines without distinction (xxvii.).
The acts of the Robber Synod were examined; fraud, violence and coercion were charged against it; its entire proceedings were annulled, and, at the third session, its leader, Dioscurus, was deposed and degraded.
The robber chief was struck by this answer.
For a year (June 68 - June 69) he held his hand and watched events, until the robber-bands of Simon Bar-Giora (son of the proselyte) required his attention.
