The Greek argyrion refers to silver, silver money, or silver coins. It is the common New Testament word for money as actual silver currency, as distinct from gold (chrysion).
Argyrion appears in several pivotal passages. The thirty pieces of silver paid to Judas for betraying Jesus (Matthew 26:15; 27:3-9) fulfill the prophecy of Zechariah 11:12-13. The coin lost in Jesus' parable (Luke 15:8-9) is likely a drachma described as argyrion. Peter declares to the lame man, 'Silver (argyrion) and gold I do not have, but what I do have I give you' (Acts 3:6). The word frames money as a potential master that competes with Christ, culminating in Jesus' warning that no one can serve both God and money (Matthew 6:24).
