The noun ἱδρώς means sweat or perspiration—the bodily fluid exuded during physical labor, heat, or stress. Classical literature frequently associates sweat with toil and effort, as in Hesiod's maxim that the gods placed sweat before virtue. Ancient medical writers also used it for tree exudations (gum, resin). Luke 22:44 describes Jesus's sweat in Gethsemane becoming "like great drops of blood"—the agony intensifying his perspiration. The image emphasizes the physical reality of Jesus's distress. Translations uniformly render it "sweat" (Spanish "sudor," French "sueur"), the straightforward bodily secretion indicating intense strain or anguish.
