Albert Barnes Commentary John 7:33

"Jesus therefore said, Yet a little while am I with you, and I go unto him that sent me." — John 7:33 (ASV)

Yet a little while am I with you. It will not be long before my death. This is supposed to have been about six months before his death. This speech of Jesus is full of tenderness. They were seeking his life. He tells them that he is fully aware of it; that he will not be long with them; and implies that they should be diligent to seek him while he was still with them. He was about to die, but they might now seek his favour and find it. When we remember that this was said to his persecutors and murderers; that it was said even while they were seeking his life, we see the peculiar tenderness of his love. Enmity, and hate, and persecution did not prevent his offering salvation to them.

I go unto him that sent me. This is one of the intimations that he gave that he would ascend to God .
