Ellicott's commentary: "to have pronounced for a severe law against common forms of sin would have been to undermine popular support, and it is this only that the rulers had to fear. To have pronounced for capital punishment would moreover have brought Him into collision with the Roman government, which reserved to itself the power of life and death. Had He uttered a word in derogation of the majesty of the Roman empire, the charge of treason. But if He had taken the laxer view, then this, like the Sabbath question, would have been a charge of breaking the Law. He would have been brought before the Sanhedrin as a false Messiah, for the true Messiah was to establish the Law"
