Matthew 27:2

In the council Jesus was free; but now all the council rising up, as appears from St. Luke, and binding him, ( Greek: detantes auton) as one certainly guilty of death, they conduct him to Pilate. All attend to repress by their authority the people, to engage Pilate to pronounce sooner the sentence, when he saw that he was condemned by the unanimous voice of the Sanhedrim, and to hinder any one from rising in his defence. There were the more anxious, 1. because about three years before, the power of life and death had been taken from them; 2. because they wished to throw the odium of the crime on another person; and lastly, because both Jew and Gentile were equally to benefit of Christ's death, so both Jew and Gentile were to concur in inflicting it; and as all were to have salvation offered them through his blood, so none were to be freed from the guilt of shedding it.
