Adam Clarke Bible Commentary

Thou hast a devil - The crowd, who made this answer, were not in the secret of the chief priests. They could not suppose that any person desired to put him to death for healing a diseased man; and therefore, in their brutish manner, they say, Thou hast a demon - thou art beside thyself, and slanderest the people, for none of them desires to put thee to death. The Codex Cyprius (K), four others, and the margin of the later Syriac, attribute this answer to the Jews, i.e. those who were seeking his life. If the reading, therefore, of οἱ Ιουδαιοι, the Jews, be received instead of ὁ οχλος, the multitude, it serves to show the malice of his enemies in a still stronger light: for, fearing lest their wish to put him to death might not be gratified, and that his teaching should prevail among the common people; to ruin his credit, and prevent his usefulness, they give out that he was possessed by a demon; and that, though he might be pitied as a miserable man, yet he must not be attended to as a teacher of righteousness. Malice and envy are ever active and indefatigable, leaving no stone unturned, no mean unused, that they may win the object of their resentment. See the note on Joh 7:26.
