Lenos refers to a winepress — the vat or trough in which grapes are trodden to extract juice. It appears 5 times in the NT, primarily in Revelation's prophetic vision of divine judgment, though Matthew 21:33 uses it in the Parable of the Tenants.
The winepress is one of the OT's most potent images of divine judgment, drawn from Isaiah 63:1-6 where God treads the winepress of His wrath alone, His garments stained with the blood of nations. Revelation picks this up in 14:19-20 and 19:15: 'He treads the winepress [lenos] of the fury of the wrath of God Almighty.' The image is violent and corporate — not individual discipline but eschatological reckoning. The blood flowing from the winepress 'rising as high as the horses' bridles for a distance of 1,600 stadia' (Revelation 14:20) evokes total, comprehensive judgment. Paradoxically, the same New Testament that speaks of the Lamb who was slain also speaks of the Lion who treads the winepress — both dimensions of Christ's work are essential to biblical theology.
