John 8:21-24 New American Standard Bible (NASB)
21 Then He said again to them, “I go away, and you will seek Me, and will die in your sin; where I am going, you cannot come.” 22 So the Jews were saying, “Surely He will not kill Himself, will He, since He says, ‘Where I am going, you cannot come’?” 23 And He was saying to them, “You are from below, I am from above; you are of this world, I am not of this world. 24 Therefore I said to you that you will die in your sins; for unless you believe that [a]I am He, you will die in your sins.”
