Matthew and John (as two of Jesus' twelve disciples) were with Him when He was betrayed, making their gospels eyewitness accounts. (Matthew 26, John 18)
Mark, though not one of the twelve, may also have been an eyewitness to the event. His gospel is the only one that makes mention of "a certain young man," in Mark 14:51, 52.
Since Mark alone records this occurrence, some surmise that the young man was Mark himself. If so, he too would have been an eyewitness.
Most biblical scholars believe that the Gospel of Matthew was not written by an eyewitness of Jesus' ministry, but by a second-generation Christian who compiled various sources, including the oral traditions of the early Christian community. It is thought to have been written between 80-90 AD.
There are four main eyewitness accounts of Jesus in the Bible, known as the Gospels of Matthew, Mark, Luke, and John.
The betrayal of Judas played a significant role in the events leading up to the crucifixion of Jesus. Judas' betrayal led to Jesus being arrested by the authorities, ultimately leading to his trial and crucifixion. This act of betrayal was a key factor in the fulfillment of the prophecy of Jesus' death and resurrection.
The accounts of the betrayal and arrest of Jesus in the Gospels of Mark, Matthew, and Luke share core elements but differ in details and emphasis. In Mark, Jesus' anguish in the Garden of Gethsemane is highlighted, and the betrayal by Judas is depicted with a sense of urgency. Matthew includes a unique detail of Judas’ remorse and the return of the thirty pieces of silver, emphasizing the theme of betrayal. Luke presents a more compassionate view of Jesus, who heals the ear of Malchus, the high priest's servant, during the arrest, emphasizing forgiveness even in the moment of betrayal.
Matthias did not play a direct role in the events surrounding the betrayal of Jesus. Matthias was chosen to replace Judas Iscariot as one of the twelve apostles after Judas betrayed Jesus. Matthias was not involved in the betrayal itself.
A kiss on the cheek from Judas.

The stories came from eyewitnesses or eyewitness accounts of his life and teachings.
If you are asking about Judas and the betrayal , then he sold Jesus to the priests for 30 pieces of silver.
The Gospel of Mark presents Jesus as a Savior-King, who conquers demons, disease, and death. He writes like an on-the-spot reporter, constantly using the present tense to create the impression of an eyewitness account. He emphasizes Jesus' mighty and miraculous works making his Gospel action-packed and vividly fresh.
Judas betrayed Jesus with a kiss as a signal to the soldiers who were arresting Jesus. This act of betrayal was part of a plan to identify Jesus to the authorities.
