John 16:17-18 NIV

[17] At this, some of his disciples said to one another, “What does he mean by saying, ‘In a little while you will see me no more, and then after a little while you will see me,’ and ‘Because I am going to the Father’?” [18] They kept asking, “What does he mean by ‘a little while’? We don’t understand what he is saying.”
