χοῖνιξ was a Greek dry measure used particularly for grain, equivalent to about one quart or roughly one liter—the typical daily bread ration for one person. It appears only in Revelation 6:6, in John's vision of the third seal judgment. The voice announces: 'A quart (χοῖνιξ) of wheat for a denarius, and three quarts (τρεῖς χοίνικες) of barley for a denarius'—depicting severe famine conditions where a full day's wage buys only enough grain for one person's basic subsistence. This is economic devastation: no surplus, nothing for family, nothing for any other needs. The χοῖνιξ becomes a unit measuring scarcity and judgment.
