{6} There was a division therefore again among the Jews for these sayings.

(6) The gospel uncovers hypocrisy, and therefore the world must necessarily rage when the gospel comes forth.

Jamieson-Fausset-Brown Bible Commentary

19-21. There was a division . again among the Jews for these sayings-the light and the darkness revealing themselves with increasing clearness in the separation of the teachable from the obstinately prejudiced. The one saw in Him only "a devil and a madman"; the other revolted at the thought that such words could come from one possessed, and sight be given to the blind by a demoniac; showing clearly that a deeper impression had been made upon them than their words expressed.

Matthew Henry's Concise Commentary

10:19-21 Satan ruins many, by putting them out of conceit with the word and ordinances. Men would not be laughed out of their necessary food, yet suffer themselves thus to be laughed out of what is far more necessary. If our zeal and earnestness in the cause of Christ, especially in the blessed work of bringing his sheep into his fold, bring upon us evil names, let us not heed it, but remember our Master was thus reproached before us.
