Passage
Then said the Jews, Will he kill himself? because he saith, Whither I go, ye cannot come.
Then said the Jews, Will he kill himself? because he saith, Whither I go, ye cannot come.
John 8:20 These words spake Jesus in the treasury, as he taught in the temple: and no man laid hands on him; for his hour was not yet come.
John 8:21 Then said Jesus again unto them, I go my way, and ye shall seek me, and shall die in your sins: whither I go, ye cannot come.
John 8:22 Then said the Jews, Will he kill himself? because he saith, Whither I go, ye cannot come.
John 8:23 And he said unto them, Ye are from beneath; I am from above: ye are of this world; I am not of this world.
John 8:24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
The verse centers on "said", "jews", "kill", "himself", "saith", "whither", and "come". It is saying that the verse draws attention to "said" and "jews", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "Then said Jesus again unto them I..." into verse 23's "And he said unto them Ye are...", so "said" and "jews" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "said" and "jews" with trust shaped by these words, not by a vague optimism outside the passage.
