John Gill Commentary John 8:22

"The Jews therefore said, Will he kill himself, that he saith, Whither I go, ye cannot come?" — John 8:22 (ASV)

Then said the Jews, will he kill himself ?
&c.] Which was not only a wicked, but a foolish consequence, drawn from his words: for it by no means followed, because he was going away, and where they could not come, that therefore he must destroy himself; this seems to be what they would have been glad he would have done, and suggested the thought that he might do it, in which they imitated Satan, (Matthew 4:6) , under whose influence they now apparently were, and hoped that he would, which would at once extricate them out of their difficulties on his account:

because he says, where I go you cannot come :
this is no reason at all; for had Christ's meaning been, as they blasphemously intimate, they might have destroyed themselves too, and have gone after him.
