Where is the biblical authority that says that Judas Iscariot was a thief who dipped into the funds?

John 12-6 says that he was a thief.

John chapter 12 verse 6 is where it is mentioned that Judas used to steal from the purse

“Scouse”, here are some points many Christian believers have overlooked when seeking to avoid error and spiritual confusion about the figure of Judas Iscariot:

1. When the shepherd boy David was anointed by the prophet Samuel to become king over Israel in place of Saul of Benjamin, David also was consecrated to serve as judge, priest, and prophet. It would be a generation later (40 years) before David would be crowned. Even so, many events in the life of David would serve as prophetic demonstrations that spoke to the life of the ruler who would be sent by GOD to establish an everlasting kingdom on the earth (we say, the Messiah; the Christ, the anointed One).

2. As a divine spokesperson David shared poetry and music (psalms) to praise GOD and proclaim sacred truth that included a description of one who would betray the coming holy priesthood and apostleship.

3. All of the disciples who gathered with Jesus to celebrate the Last Passover, and who also shared in his introduction of the Lord’s Supper, had been “called” (selected) by Jesus himself to become a part of his ministry. They were always with him on a daily basis except (1.) when sent on missions to prepare the towns and villages for his coming; or (2.) when sent to minister themselves (i.e., cast out unclean spirits; heal; preach; raise the dead).

4. Approaching the time of Jesus being arrested and crucified, many among the crowds and followers became offended by his teaching that all must eat his body and drink his blood, and so began to turn away. Like those who trusted Moses completely, followed him through the Red Sea, yet, questioned his authority and integrity days later, all of the apostles became uncertain of their own true commitment to the Lord. They knew within themselves they were still willing to quit, and go back home. Thus, consider again the following that use language from the Bible:

(1.) John 6: 63-71, King James Version (KJV): 63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. 64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. 65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father. 66 From that time many of his disciples went back, and walked no more with him. 67 Then said Jesus unto the twelve, Will ye also go away? 68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. 69 And we believe and are sure that thou art that Christ, the Son of the living God. 70 Jesus answered them, Have not I chosen you twelve, and one of you is a devil? 71 He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.

(2.) John 12: 1-8, KJV: 1 Then Jesus six days before the passover came to Bethany, where Lazarus was, which had been dead, whom he raised from the dead. 2 There they made him a supper; and Martha served: but Lazarus was one of them that sat at the table with him. 3 Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odour of the ointment. 4 Then saith one of his disciples, Judas Iscariot, Simon’s son, which should betray him, 5 Why was not this ointment sold for three hundred pence, and given to the poor? 6 This he said, not that he cared for the poor; but because he was a thief, and had the bag, and bare what was put therein. 7 Then said Jesus, Let her alone: against the day of my burying hath she kept this. 8 For the poor always ye have with you; but me ye have not always.

(3.) Mark 14: 18-21, KJV: 18 And as they sat and did eat, Jesus said, Verily I say unto you, One of you which eateth with me shall betray me. 19 And they began to be sorrowful, and to say unto him one by one, Is it I? and another said, Is it I? 20 And he answered and said unto them, It is one of the twelve, that dippeth with me in the dish. 21 The Son of man indeed goeth, as it is written of him: but woe to that man by whom the Son of man is betrayed! good were it for that man if he had never been born.

There is far more to be said, correctly examined, and spiritually apprehended. (For example, (4.) 1st John 4: 1-6, KJV: 1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. 2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: 3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. 4 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. 5 They are of the world: therefore speak they of the world, and the world heareth them. 6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.) Even so, I trust this fragment will be useful. Be it unto you according to your faith.

He acted as the "hand of god" in that without the directive from Jesus there would have been no "crucifixion" for them to venerate today.

John 12:6

there is a verse which says Judas bought a brand new coat. and usually thieves think they have RESPECT when they look rich, but stealing to get the appearance of respect and wealth is still a crime.

John 12:6 "Now he said this, not because he was concerned about the poor, but because he was a thief, and as he had the money box, he used to pilfer what was put into it."

John 12:3-6.

"Then Mary took about a pint of pure nard, an expensive perfume; she poured it on Jesus’ feet and wiped his feet with her hair. And the house was filled with the fragrance of the perfume.But one of his disciples, Judas Iscariot, who was later to betray him, objected, 'Why wasn’t this perfume sold and the money given to the poor? It was worth a year’s wages.' He did not say this because he cared about the poor but because he was a thief; as keeper of the money bag, he used to help himself to what was put into it."

It doesn't matter. It's fiction
