According to Matthew, Judas received thirty pieces of silver for betraying Jesus.
In Matthew 26, Judas Iscariot approached the chief priests and asked what they would give him to hand Jesus over. They offered thirty pieces of silver, after which Judas looked for an opportunity to identify Jesus to the authorities. The payment became a central detail in later Christian interpretation of the Passion narrative.
Matthew later uses the same amount in the account of Judas’s remorse. After Jesus was condemned, Judas returned the money to the chief priests and elders. Matthew connects the thirty pieces with a passage from the Book of Zechariah, although the wording and interpretation of that connection have been discussed by scholars.
The amount is sometimes confused with the broader phrase “thirty pieces of silver,” which became a general symbol of betrayal. The Gospel accounts differ in some details about Judas’s death and the handling of the money, so Matthew’s specific payment should not be treated as a detail stated identically in every Gospel.
