Passage
I speak not of you all. I know those whom I have chosen; but that the scripture might be fulfilled, He that eats bread with me has lifted up his heel against me.
I speak not of you all. I know those whom I have chosen; but that the scripture might be fulfilled, He that eats bread with me has lifted up his heel against me.
John 13:16 Verily, verily, I say to you, The bondman is not greater than his lord, nor the sent greater than he who has sent him.
John 13:17 If ye know these things, blessed are ye if ye do them.
John 13:18 I speak not of you all. I know those whom I have chosen; but that the scripture might be fulfilled, He that eats bread with me has lifted up his heel against me.
John 13:19 I tell you [it] now before it happens, that when it happens, ye may believe that I am [he].
John 13:20 Verily, verily, I say to you, He who receives whomsoever I shall send receives me; and he that receives me receives him who has sent me.
The verse centers on "speak", "chosen", "scripture", "might", "fulfilled", "eats", "bread", and "lifted". It is saying that the verse draws attention to "speak" and "chosen", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "If ye know these things blessed are..." into verse 19's "I tell you it now before it...", so "speak" and "chosen" 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 "speak" and "chosen" with trust shaped by these words, not by a vague optimism outside the passage.
