John 16:18-19 ESV
So they were saying, “What does he mean by ‘a little while’? We do not know what he is talking about.” Jesus knew that they wanted to ask him, so he said to them, “Is this what you are asking yourselves, what I meant by saying, ‘A little while and you will not see me, and again a little while and you will see me’?
