SWEAT
Sweat appears on the body as a reaction to eliminate excess heat or energy consumed in arduous effort, reestablishing its thermal balance thanks to the heat consumed in the evaporation of sweat.
In medicine, a special form of sweat is known, blood sweat (hematidrose, or diapedesis), in which, as a result of violent emotion or great mental excitement, blood corpuscles escape from the blood vessels without breaking them, and pass through the pores of the skin.
During the agony in Gethsemane, Christ’s sweat fell to the ground in great drops of blood (Lk. 22:44). This illustrates his deep anxiety before the terrible trial that He, holy and blameless, was going to suffer, being made sin and curse for us on the Cross (2 Cor. 5:21; Gal. 3:13).
