Adam Clarke on John 14:29

I have told you before it come to pass - Lest my death should be a stumbling-block to you, I have spoken of it beforehand, and showed you the necessity of it, that when it happens ye may believe, that as I could predict it so clearly, and so circumstantially, so all the good which I have promised shall be the result may be confidently expected by you; and that your sorrow, if not entirely removed, may at least be much mitigated.
