In John 13:10, Jesus is washing his friends' feet on his last night. Peter asks to be washed all over. Jesus says a person who has bathed only needs his feet washed, and is clean. Then he adds, "but not all," because Judas, who would betray him, was at the table.
It was the last night before Jesus was arrested. He was eating supper with his twelve closest friends in a room in Jerusalem. The Gospel of John tells what happened during the meal, in chapter 13.
Jesus got up from the table. He took off his outer robe and tied a towel around his waist. He poured water into a basin and began to wash his friends' feet, one by one. In that time, washing feet was the job of the lowest servant in a house.
When he came to Peter, Peter refused. "Thou shalt never wash my feet." Jesus told him that if he did not let him, Peter would have no part with him. So Peter swung all the way the other way. Wash my hands and my head too, he said.
Jesus answered him.
Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
John 13:10 · King James Version
Clean already
Someone who has had a bath only needs to wash the dust off his feet after walking. Jesus was telling Peter he already belonged to him. He did not need to be scrubbed from head to foot.
But not all
The Gospel of John says Jesus knew who would betray him. That is why he said not all. Judas was sitting right there. Jesus knelt at that table in front of every one of them.
What it means
The teacher did the servant's work. He did it for the man who would hand him over that same night. He did not skip him.
If you feel you do not deserve kindness from God, he knelt in front of Judas too.

1Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end.
2And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon’s son, to betray him;
3Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;
4He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
5After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
6Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet?
7Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
8Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
9Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
10Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
11For he knew who should betray him; therefore said he, Ye are not all clean.
12So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you?
13Ye call me Master and Lord: and ye say well; for so I am.
14If I then, your Lord and Master, have washed your feet; ye also ought to wash one another’s feet.
15For I have given you an example, that ye should do as I have done to you.
16Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him.
17If ye know these things, happy are ye if ye do them.
18¶ I speak not of you all: I know whom I have chosen: but that the scripture may be fulfilled, He that eateth bread with me hath lifted up his heel against me.
19Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
20Verily, verily, I say unto you, He that receiveth whomsoever I send receiveth me; and he that receiveth me receiveth him that sent me.
21When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.
22Then the disciples looked one on another, doubting of whom he spake.
23Now there was leaning on Jesus’ bosom one of his disciples, whom Jesus loved.
24Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spake.
25He then lying on Jesus’ breast saith unto him, Lord, who is it?
26Jesus answered, He it is, to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon.
27And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
28Now no man at the table knew for what intent he spake this unto him.
29For 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.
30He then having received the sop went immediately out: and it was night.
31¶ Therefore, when he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him.
32If God be glorified in him, God shall also glorify him in himself, and shall straightway glorify him.
33Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you.
34A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
35By this shall all men know that ye are my disciples, if ye have love one to another.
36¶ Simon Peter said unto him, Lord, whither goest thou? Jesus answered him, Whither I go, thou canst not follow me now; but thou shalt follow me afterwards.
37Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake.
38Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.
