John Chrysostom
He did not say by whom those men had been destroyed, but simply, “they were scattered.” Perhaps he considered it unnecessary to speak of that.
He does not present ancient examples, though he had them. He points to recent ones, which could persuade with special force. Therefore he speaks indirectly: “not long before this,” as if saying, a few days ago.
If he had said directly, “Release these men,” he would have drawn suspicion on himself, and his speech would not have had such force. Through examples, however, it received proper force.
For this reason he recalls not one example, but a second also, though he could have brought forward a third. By their abundance he shows the justice of his words and turns them away from their murderous intention.
“After him Judas appeared.” You may learn about this in greater detail from the books of Josephus, who sets out the history of these events carefully: Antiquities of the Jews, book 18, chapter 1, and book 20, chapter 2.
