John 16:16 - Matthew Poole's English Annotations on the Holy Bible

I must die, and so for two or three days you shall not see me; but after that you shall see me again, when I shall be risen from the dead: but because of the last words, because I go to the Father, which seem to give a reason of the first clause; possibly by the little while first mentioned, our Saviour means the whole time from the speaking of those words to his ascension into heaven, for all that time was not more than six weeks; and by the little while mentioned in the latter part of the verse, our Saviour intends the whole time from his ascension until his coming to judgment: and so the reason is proper which is added, because I go unto the Father; for being so ascended, and sat down at the right hand of God, we are told that there he must sit, till God hath made all his enemies his footstool; and by the apostle, that the last enemy to be destroyed is death; and, Acts 3:21, Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
