“But these things have I told you, that when the time shall come, ye may remember that I told you of them. And these things I said not unto you at the beginning, because I was with you.”
John 16:4 — Greek Interlinear
Church Fathers on John 16:4
After the promise of the Holy Spirit, to inspire them with strength to give witness; He well adds, These things have I spoken to you, that you should not be offended. For when the love of God is shed abroad in our hearts by the Holy Spirit which is given to us (Romans 5:5), then great peace have they that love God’s law, and they are not offended at it (Psalms 118). What they were about to suffer follows next: They shall put you out of the synagogues.
For the Jews had already agreed, if any confessed that He was Christ, that he should be put out of the synagogue.
