Reference excerpt

Thirty pieces of silver was the price for which Judas Iscariot betrayed Jesus, according to an account in the Gospel of Matthew 26:15 in the New Testament. Before the Last Supper, Judas is said to have gone to the chief priests and agreed to hand over Jesus in exchange for 30 silver coins and to have attempted to return the money afterwards, filled with remorse. The Gospel of Matthew claims that the subsequent purchase of the potter's field was fulfilment by Jesus of a prophecy of Zechariah. The image has often been used in artwork depicting the Passion of Christ. The phrase is used in literature and common speech to refer to people "selling out", compromising a trust, friendship, or integrity for personal gain.

Biblical narrative According to the Gospel of Matthew, Judas Iscariot was a disciple of Jesus. Before the Last Supper, Judas went to the chief priests and agreed to hand over Jesus in exchange for 30 silver coins. Jesus was then arrested in Gethsemane, where Judas revealed Jesus's identity to the soldiers by giving him a kiss. According to Chapter 27 of Matthew's gospel, Judas was filled with remorse and returned the money to the chief priests before hanging himself. The chief priests decided that they could not put it into the temple treasury as it was considered blood money, and so with it they bought the Potter's Field. A different account of the death of Judas is given in the Book of Acts 1:17–20; in it, Peter is quoted as saying: "With the payment he received for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out." Although the Gospel of Luke, which is commonly thought to have been written by the same author as Acts, mentions in 22:3–6 that Judas and the chief priests and temple guard officers agreed on a price, the amount is not specified, nor is the money paid up front as in Matthew.

Types of coin

The word used in Matthew 26:15 (ἀργύρια, argyria) simply means "silver coins", and scholars disagree on the type of coins that would have been used. Donald Wiseman suggests two possibilities. They could have been tetradrachms of Tyre, usually referred to as Tyrian shekels (14 grams of 94% silver), or staters from Antioch (15 grams of 75% silver), which bore the head of Augustus. Alternatively, they could have been Ptolemaic tetradrachms (13.5 ± 1 g of 25% silver). There are 31.1035 grams per troy ounce. At spot valuation of $35/ozt in 2025, 30 "pieces of silver" would be worth approximately $114 to $552 in present-day value (USD) depending on which coin was used.

The Tyrian shekel weighed four Athenian drachmas, about 14 grams, more than earlier 11-gram Israeli shekels, but was regarded as the equivalent for religious duties at that time. Because Roman coinage was only 80% silver, the purer (94% or more) Tyrian shekels were required to pay the temple tax in Jerusalem. The money changers referenced in the New Testament Gospels (Matt. 21:12 and parallels) exchanged Tyrian shekels for common Roman currency. The Athenian tetradrachm ("four drachmae") coin from the 5th century BC was likely the most widely used coin in the Greek world before the time of Alexander the Great, alongside the Corinthian stater. It featured the helmeted profile bust of Athena on the obverse (front) and an owl on the reverse (back). In daily use they were called γλαῦκες glaukes (owls), hence the proverb Γλαῦκ’ Ἀθήναζε, 'an owl to Athens', referring to something that was in plentiful supply, like 'coals to Newcastle'. The reverse is featured on the national side of the modern Greek 1 euro coin. Drachmae were minted on different weight standards at different Greek mints. The standard that came to be most commonly used was the Athenian or Attic one, which weighed a little over 4.3 grams. A drachma was approximately a day's pay for a skilled laborer. So 30 pieces of silver (30 tetradrachm), at four drachmas each, would roughly be comparable to four months' (120 days) wages. In the medieval period some religious institutions displayed ancient Greek coins of the island of Rhodes as specimens of the Thirty Pieces of Silver. The obverses of these coins showed a facing head of the sun god Helios, with rays projecting around the upper part of it. These rays were interpreted as a representation of the Crown of Thorns. The extracanonical Narrative of Joseph of Arimathea records that Judas was paid 30 pieces of gold, not silver.

Theological interpretation In Zechariah 11:12–13, 30 pieces of silver is the price Zechariah receives for his labour. He takes the coins and throws them "to the potter". Klaas Schilder notes that Zechariah's payment indicates an assessment of his worth, as well as his dismissal. In Exodus 21:32, 30 pieces of silver was the price of a slave, so while Zechariah calls the amount a "handsome price" (Zechariah 11:13), this could be sarcasm. Barry Webb, however, calls it as a "considerable sum of money". Schilder suggests that these 30 pieces of silver then get "bandied back and forth by the Spirit of Prophecy." When the chief priests decide to buy a field with the returned money, Matthew says that this fulfilled "what was spoken by Jeremiah the prophet." Namely, "They took the thirty silver coins, the price set on him by the people of Israel, and they used them to buy the potter's field, as the Lord commanded me" (Matthew 27:9–10). Although many scholars see Jeremiah's name as included in error, Jeremiah's purchase of a field in Jeremiah 32 may indicate that both prophets are in mind. Craig Blomberg argues that Matthew is using typology in his quotation, rather than "any kind of single or double fulfillment of actual predictive prophecy". According to Blomberg's more charitable interpretation, Matthew is telling his readers that, "like Jeremiah and Zechariah, Jesus attempts to lead his people with a prophetic and pastoral ministry, but instead he ends up suffering innocently at their hands". William Hendriksen argues that Matthew is referring to Jeremiah 19. Blomberg also suggests that Matthew may also be saying that "Jesus' death is a ransom, the price paid to secure a slave's freedom", and that the use of the blood money to buy a burial ground for foreigners (Matthew 27:7) may hint at the idea that "Jesus' death makes salvation possible for all the peoples of the world, including the Gentiles". The Handy Book for Bible Readers (1877) states that:

Worked examples

Example 1 — a first encounter with Thirty pieces of silver

Start with the simplest possible case. Write down what Thirty pieces of silver claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thirty pieces of silver before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thirty pieces of silver ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thirty pieces of silver

In research
