This is true. Though Judas was unclean and had not believed from the beginning and Jesus
knew he was going to betray him, fulfilling prophecy in doing so, Jesus still called him "friend."
“Jesus answered them, Have not I
chosen you twelve, and
one of you is a devil? He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.”
John 6:70-71 KJV
“I have manifested thy name unto
the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word. ……While I was with them in the world, I kept them in thy name:
those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.”
John 17:6, 12
“Then one of the twelve, called
Judas Iscariot, went unto the chief priests, and said unto them, What will ye give me, and I will deliver him unto you?
And they
covenanted with him for thirty pieces of silver. And from that time
he sought opportunity to betray him.”
Matthew 26:14-16 KJV
“And I said unto them,
If ye think good, give me my price; and if not, forbear. So
they weighed for my price thirty pieces of silver. And the LORD said unto me,
Cast it unto the potter: a goodly price that I was prised at of them. And I took the thirty pieces of silver, and cast them to the potter in the house of the LORD.”
Zechariah 11:12-13 KJV
“Then
Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, saying, I have sinned in that I have betrayed the innocent blood.
And they said, What is that to us? see thou to that. And
he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
And
the chief priests took the silver pieces, and said, It is not lawful for to put them into the treasury,
because it is the price of blood. And they took counsel, and
bought with them the potter's field, to bury strangers in. Wherefore that field was called, The field of blood, unto this day.
Then was fulfilled that which was spoken by Jeremy the prophet, saying, And
they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value; and gave them for the potter's field, as the Lord appointed me.”
Matthew 27:3-10 KJV
“And supper being ended,
the devil having now put 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 was come
from God, and went
to God;
….For
he knew who should betray him; therefore said he, Ye are not all clean. So
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? For
I have given you an example, that ye should do as I have done to you.
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. Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
When 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.
….Jesus 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. And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly. Now no man at the table knew for what intent he spake this unto him. ….He then
having received the sop went immediately out: and it was night. Therefore, when he was gone out, Jesus said,
Now is the Son of man glorified, and God is glorified in him. If God be glorified in him, God shall also glorify him in himself, and shall straightway glorify him.
A
new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.”
John 13:2-3, 11-12, 15, 18-19, 21, 26-28, 30-32, 34-35 KJV
