That wasn't said in the last supper.
You know the post I responded to below and asked for verse
You haven't quoted it either.
>>At the last supper, Jesus asked his disciples/apostles,
and I paraphrase, 'How can you say you love me if you don't obey my commandments. <<
Yes, you asked for the verse and when I showed Joh 14:15 you said it is not a quote. Of which his words or of the bible?
Also when you said >>That wasn't said in the last supper.<< you were wrong.
Joh 13:1
Now before the Feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.
Joh 13:2
And supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon's son, to betray Him,
Joh 13:5 After that, He poured water into a basin and
began to wash the disciples' feet, and to wipe them with the towel with which He was girded.
Washing of their feet was done in upper room
Joh 13:21 When Jesus had said these things, He was troubled in spirit, and testified and said, "
Most assuredly, I say to you, one of you will betray Me."
Judas was to betray Him
Joh 13:27 Now after the piece of bread, Satan entered him. Then Jesus said to him, "
What you do, do quickly."
Judas went to betray Christ Jesus
Start of the Upper Room Discourse
Joh 13:31 So, when he had gone out,
Jesus said, "Now the Son of Man is glorified, and God is glorified in Him.
Joh 14:15 "
If you love Me, keep My commandments.
The High Priestly Prayer. This was done by Christ Jesus in the upper room
Betrayal and Arrest of Jesus
Joh 18:1
When Jesus had spoken these words,
He went out with His disciples over the Brook Kidron, where there was a garden, which He and His disciples entered.
Note that after Christ Jesus had finished speaking that was when they left the upper room and went to the garden where Christ was betrayed.
So the verse that I posted was indeed spoken in the upper room at the last supper by Christ Jesus and it fits with the paraphrase.
