The Greek word plýnō, represented by G4150, means to "plunge" or launder clothing. Derived from an obsolete term for "to flow," its specific application is to wash. This word is exceptionally rare, appearing only 1 time across 1 unique verse in the Bible.
The sole use of G4150 is found in a highly symbolic context within the book of Revelation. It describes the saints who have emerged from a period of intense suffering, stating they "have washed their robes, and made them white in the blood of the Lamb" Revelation 7:14. Here, the act of washing is not a literal cleansing with water but a spiritual purification achieved through a paradoxical agent: blood.
Several related words are essential to understanding the context of G4150:
- G3021 leukaínō (to whiten): This word describes the direct result of the washing in Revelation 7:14. The robes are not just cleansed; they are actively made white, a state of purity that, according to Mark 9:3, no earthly fuller could achieve.
- G129 haîma (blood): This is the cleansing agent used to wash the robes. The concept of blood as a means of redemption and forgiveness is a consistent theme, as seen in Ephesians 1:7 and Revelation 5:9.
- G721 arníon (lamb): This word identifies the source of the purifying blood. The Lamb is a central figure in Revelation, whose sacrifice enables overcoming and redemption Revelation 12:11.
The theological weight of G4150 is concentrated in its single, powerful appearance.
- Atoning Purification: The action of washing robes in blood G129 is a profound metaphor for salvation. It signifies a cleansing from sin that is only possible through the atoning sacrifice of the Lamb G721.
- Righteousness through Faith: Those who wash their robes are the ones who have come out of "great tribulation" Revelation 7:14. This act represents their identification with Christ's death, resulting in their robes being made white G3021, a symbol of imputed righteousness.
- Victory and Overcoming: The context connects this cleansing with ultimate victory. As stated in Revelation 12:11, the saints overcome by the blood of the Lamb G721 and their testimony.
In summary, while G4150 appears only once, its use in Revelation 7:14 is pivotal. It encapsulates a core tenet of Christian theology: spiritual purification and righteousness are not achieved through ordinary means but through the paradoxical and powerful cleansing found in the blood of the Lamb. It transforms a common word for washing into a symbol of ultimate redemption.
