John Lightfoot on Luke 13:33

[It cannot be that a prophet perish, &c.] "A tribe, nor false prophet, [such a one they accounted the holy Jesus,] nor a high priest, can be judged but by the bench of seventy-one." Rambam upon the place, as also the Gemara; "We know that a false prophet must be judged by the Sanhedrim, from the parity of the thing: for so is judged a rebellious judge."

Now as to the judgment itself, these things are said: "They do not judge him to death in the court of judicature, that is, in his own city, nor in that that is at Jabneh; but they bring him to the great Consistory that is at Jerusalem, and reserve him to one of their feasts; and at their feast they execute him, as it is said, 'All Israel shall hear, and shall fear, and do no more so.'"
