Sweat — the physical evidence of extreme exertion or anguish. Used only once in the NT, in the most intense moment of Jesus' pre-crucifixion suffering.
Luke 22:44 records Jesus' sweat becoming 'like great drops of blood' in Gethsemane. This single use of hidrōs connects directly to Genesis 3:19: 'By the sweat of your face you shall eat bread.' The curse of Eden included sweat as the mark of toil and mortality. In Gethsemane, Jesus sweats the curse into Himself — the Second Adam bearing in His body what the first Adam brought upon humanity. The sweat of the garden is reversed by sweat in the Garden.
