Passage
For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.
For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.
John 13:27 And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
John 13:28 Now no man at the table knew for what intent he spake this unto him.
John 13:29 For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.
John 13:30 He then having received the sop went immediately out: and it was night.
John 13:31 Therefore, when he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him.
The verse centers on "some", "thought", "judas", "jesus", "said", "things", "need", and "against". It is saying that the verse draws attention to "some" and "thought", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 28's "Now no man at the table knew..." into verse 30's "He then having received the sop went...", so "some" and "thought" 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 "some" and "thought" with trust shaped by these words, not by a vague optimism outside the passage.
