This conversation probably took place while they were waiting for the host to serve the
main evening meal:

Luke 22.24-30 (NKJV), "But there was also rivalry among them, as to which of them should be
considered the greatest.  And He said to them, "The kings of the Gentiles exercise lordship over them,
and those who exercise authority over them are called ‘benefactor’.  But not so among you; on the
contrary, he who is greatest among you, let him be as the younger, and he who governs as he who
serves.  For who is greater, he who sits at the table, or he who serves?  Is it not he who sits at the
table?  Yet I am among you as the One who serves.  But you are those who have continued with Me in
My trials.  And I bestow upon you a kingdom, just as My Father bestowed one upon Me, that you may
eat and drink at My table in My kingdom, and sit on thrones judging the twelve tribes of Israel.'"

Let us observe what happened next:

John 13:2-20 (NKJV), "And supper being ended, the devil having already put it into the heart of Judas
Iscariot, Simon's son, to betray Him, Jesus, knowing that the Father had given all things into His
hands, and that He had come from God and was going to God,
rose from supper and laid aside His
garments, took a towel and girded Himself.  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.  Then He came to
Simon Peter.  And Peter said to Him, "Lord, are You washing my feet?"  Jesus answered and said to
him, "What I am doing you do not understand now, but you will know after this."  Peter said to Him,
"You shall never wash my feet!"  Jesus answered him, "If I do not wash you, you have no part with
Me."  Simon Peter said to Him, "Lord, not my feet only, but also my hands and my head!"  Jesus said
to him, "He who is bathed needs only to wash his feet, but is completely clean; and you are clean, but
not all of you.”  For He knew who would betray Him; therefore He said, "You are not all clean.”  So
when He had washed their feet, taken His garments, and sat down again, He said to them, "Do you
know what I have done to you?”  You call me Teacher and Lord, and you say well, for so I am.  If I
then, your Lord and Teacher have washed your feet, you also ought to wash one another's feet.  For I
have given you an example, that you should do as I have done to you.  Most assuredly, I say to you, a
servant is not greater than his master; nor is he who is sent greater than he who sent him.  If you
know these things, happy are you if you do them.  I do not speak concerning all of you.  I know whom
I have chosen; but that the Scripture may be fulfilled, 'He who eats bread with Me has lifted up his
heel against Me’.  Now I tell you before it comes, that when it does come to pass, you may believe that
I am He.  Most assuredly, I say to you, he who receives whomever I send receives Me; and he who
receives Me receives Him who sent Me."

"Supper being ended"
has been a problem phrase throughout the centuries.  Some believe it
"during supper".  It seems unlikely that Christ would have gotten up to wash the
disciples feet in the middle of the main course for supper.  Adam Clarke says, “While
supper was preparing”.  The words “was being” can be translated “begin to be” but it can
also mean, “finished”.  Notice the definition that follows:

Online Bible:
1096 ginomai ginomai ghin’-om-ahee

a prolongation and middle voice form of a primary verb; TDNT-1:681,117; v

AV-be 255, come to pass 82, be made 69, be done 63, come 52, become 47, God forbid + 3361 15,
arise 13, have 5, be fulfilled 3, be married to 3, be preferred 3, not tr 14, misc 4, vr done 2; 678

1) to become, i.e. to come into existence, begin to be, receive being
2) to become, i.e. to come to pass, happen
2a) of events
3) to arise, appear in history, come upon the stage
3a) of men appearing in public
4) to be made, finished
4a) of miracles, to be performed, wrought
5) to become, be made

Now notice in Mark 6:2 that Strong uses the same numbers, for “was come” that he does
for “being ended” in John 13:2.  The first example indicates the beginning and the second
example indicates the ending.  This seems contradictory.  However, the meaning of the
word can denote something that begins to be as well as something that is finished.  The
context must determine for us, which definition is correct.  If the immediate context does
not reveal the answer, we can look in the greater context.

Mark 6:2 And when the Sabbath day was come <1096> (5637), he began to teach in the synagogue:
and many hearing [him] were astonished, saying, From whence hath this [man] these things?  And
what wisdom [is] this which is given unto him, that even such mighty works are wrought by his

John 13:2 And supper
being ended <1096> (5637), the devil having now put into the heart of Judas
Iscariot, Simon’s [son], to betray him;

They were apparently sitting on couches around the table as they talked and waited for
the meal to arrive, expecting it any minute.  They would eat their meal while reclining on
these couches.  There could have been some appetizers on the table, for enjoyment, as
they waited for the main course.  At any rate, Christ arose from the “supper table” and
initiated the humility service.  They had probably all washed their hands earlier before the
meal, but Christ was inspired to wash their feet, probably because of the contention they
were having, before the meal began, about who was the greatest – as well as Judas' self-
serving attitude during the last few days and throughout that evening.
