Matthew Henry on John 10:19-21
We have here an account of the people's different sentiments concerning Christ, on occasion of the foregoing discourse; there was a division, a schism, among them; they differed in their opinions, which threw them into heats and parties. Such a ferment as this they had been in before (Joh 7:43; Joh 9:16); and where there has once been a division again. Rents are sooner made than made up or mended. This division was occasioned by the sayings of Christ, which, one would think, should rather have united them all in him as their centre; but they set them at variance, as Christ foresaw, Luk 12:51.

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.

They believed him to be possessed by a demon, who deranged his faculties, and that he must have been a wicked man, and a deceiver, thus to be put under the power of such a spirit.
John Gill on John 10:20
And many of them said, he hath a devil, and is mad,.... It was a notion of the Jews, that madness or distraction was from the devil, and therefore these two are here joined together, having a devil, and being mad: there is a spirit which they call Tazazith, and which, they say (z), is an evil spirit that takes away the understanding of men; and under the influence of such a "demon", the Jews thought Christ to be: and therefore say,
why hear ye him? he is a lunatic, he is distracted, he is a madman; how can you bear to hear such ranting blasphemous stuff, which no man in his, senses would ever utter? nor is anything he says to be regarded, since he is not in his right mind; but is under the…
