John 10:19-21 - Joseph Benson’s Commentary on the Old and New Testaments

There was a division among the Jews These sayings of our Lord “affected the minds of the Jews differently, for some of them cried out that he was possessed and mad, and that it was folly to hear him; others, judging more impartially of him and his doctrine, declared that his discourses were not the words of a lunatic, nor his miracles the works of a devil. Moreover, they asked his enemies if they imagined any devil was able to impart the faculty of sight to one that was born blind alluding to the astonishing cures which Jesus had lately performed.” Macknight.
