John 7:33-36 Then Jesus said to them, “I shall be with you a little while longer, and then I go to Him who sent Me. You will seek Me and not find Me, and where I am you cannot come.” Then the Jews said among themselves, “Where does He intend to go that we shall not find Him?

John 16:16-19 “A little while, and you will not see Me; and again a little while, and you will see Me, because I go to the Father.” Then some of His disciples said among themselves, “What is this that He says to us, ‘A little while, and you will not see Me; and again a little while, and you will see Me’; and, ‘because I go to the Father’?” They said therefore, “What is this that He says, ‘A little while’? We do not know what He is saying.” Now Jesus knew that they desired to ask Him, and He said to them, “Are you inquiring among yourselves about what I said, ‘A little while, and you will not see Me; and again a little while, and you will see Me’?
