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'?" (NIV)

So some of His disciples questioned among themselves, What does He mean when He tells us, In a little while you will no longer see Me, and again after a short while you will see Me, and, Because I go to My Father? (AMP)

Then said some of his disciples among themselves, What is this that he saith unto us, A little while, and ye shall not see me: and again, a little while, and ye shall see me: and, Because I go to the Father? (KJV)
