John Gill's Exposition of the Whole Bible
Luke 22:44
And being in an agony,.... Or in a conflict, and combat; that is, with thee devil, who now appeared visibly to him, in an horrible form: after his temptations in the wilderness Satan left him for a season, till another opportunity should offer; and now it did; now the prince of this world came to him; see Luke 4:13 and attacked him in a garden, where the first onset on human nature was made: and now began the battle between the two combatants, the serpent, and the seed of the woman; which issued in the destruction of Satan, and thee recovery of mankind. The Arabic version leaves out this clause; and the Syriac version renders it, "being in fear"; and to the same purpose are the Persic and Ethiopic versions; that is, of death; and must be understood of a sinless fear of death in his human nature, to which death, being a dissolution of it, must be disagreeable; though not death, barely considered, was the cause of this fear, distress, and agony he was in; but as it was to be inflicted on him for the sins of his people, which he bore, and as it was the curse of the law, and the effect of divine wrath and displeasure:
he prayed more earnestly; repeating the words he had said before with great eagerness and importunity, with intenseness of mind, and fervour of Spirit, with strong crying, and tears to him that was able to save him from death, Hebrews 5:7
and his sweat was, as it were, great drops of blood falling to the ground. This account of Christ's bloody sweat is only given by Luke, who being a physician, as is thought, more diligently recorded things which belonged to his profession to take cognizance of; nor should it be any objection to the truth and credibility of this fact, that it is not mentioned by the other evangelists, since it is no unusual thing with them for one to record that which is omitted by another; nor that this is wanting in some Greek and Latin copies, as Jerom w and Hilary x observe; since it was expunged, as is supposed, either by some orthodox persons, who weakly thought it might seem to favour the Arians, who denied that Christ was of the same impassible nature with the Father; or rather by the Armenians, or by a set of men called "Aphthartodocetae", who asserted the human nature of Christ to be incorruptible: but certain it is, that it is in the most ancient and approved copies, and in all the Oriental versions, and therefore to be retained; to which may be added, that it is taken notice of, not to mention others, by those two early writers, Justin Martyr y, and Irenaeus z; nor should its being so strange and unusual a sweat at all discredit the history of it, since there have been instances of this kind arising from various causes; and if there had been none, since the case of our Lord was singular, it ought to be credited. This bloody sweat did not arise from a cachexy, or ill state of body, which has sometimes been the cause of it, as Aristotle observes, who says a, that the blood sometimes becomes sanious, and so serous, insomuch that some have been covered with a "bloody sweat": and in another place he says b, that through an ill habit of body it has happened to some, that they have sweat a bloody excrement. Bartholinus produces instances in plagues and fevers c; but nothing of this kind appears in Christ, whose body was hale and robust, free from distempers and diseases, as it was proper it should, in order to do the work, and endure the sufferings he did; nor did it arise from any external heat, or a fatiguing journey. The above writer d a relates, from Actuarius, a story of a young man that had little globes of blood upon his skin, by sweat, through the heat of the sun, and a laborious journey. Christ's walk from Jerusalem to the garden was but a short one; and it was in the night when he had this sweat, and a cold night too; see John 18:18, it rather arose from the agony in which he was, before related: persons in an agony, or fit of trembling, sweat much, as Aristotle observes e; but to sweat blood is unusual. This might be occasioned by his vehement striving and wrestling with God in prayer, since the account follows immediately upon that; and might be owing to his strong cries, to the intenseness and fervour of his mind, and the commotion of the animal spirits, which was now very great, as some have thought; or, as others, to the fear of death, as it was set before him in so dreadful a view, and attended with such horrible circumstances. Thuanus f, a very grave and credible historian, reports of a governor of a certain garrison, who being, by a stratagem, decoyed from thence, and taken captive, and threatened with an ignominious death, was so affected with it, that he sweat a "bloody sweat" all over his body. And the same author g relates of a young man of Florence, who being, by the order of Pope Sixtus the Fifth, condemned, as he was led along to be executed, through the vehemence of his grief discharged blood instead of sweat, all over his body: and Maldonate, upon this passage, reports, that he had heard it from some who saw, or knew it, that at Paris, a man, robust, and in good health, hearing that a capital sentence was pronounced upon him, was, at once, all over in a bloody sweat: which instances show, that grief, surprise, and fear, have sometimes had such an effect on men; but it was not mere fear of death, and trouble of mind, concerning that, which thus wrought on our Lord, but the sense he had of the sins of his people, which were imputed to him, and the curse of the righteous law of God, which he endured, and especially the wrath of God, which was let into his soul: though some have thought this was owing to the conflict Christ had with the old serpent the devil; who, as before observed, now appeared to him in a frightful forth: and very remarkable is the passage which Dr. Lightfoot, and others, have cited from Diodorus Siculus, who reports of a certain country, that there are serpents in it, by whose bites are procured very painful deaths; and that grievous pains seize the person bitten, and also "a flow of sweat like blood". And other writers h make mention of a kind of asp, or serpent, called "Haemorrhois"; which, when it bites a man, causes him to sweat blood: and such a bloody sweat it should seem was occasioned by the bite of the old serpent Satan, now nibbling at Christ's heel, which was to be bruised by him: but of all the reasons and causes of this uncommon sweat, that of Clotzius is the most strange, that it should arise from the angels comforting and strengthening him, and from the cheerfulness and fortitude of his mind. This writer observes, that as fear and sorrow congeal the blood, alacrity and fortitude move it; and being moved, heat it, and drive it to the outward parts, and open a way for it through the pores: and this he thinks may be confirmed from the fruit and effect of Christ's prayer, which was very earnest, and was heard, as is said in Hebrews 5:7 when he was delivered from fear; which deliverance produced joy, and this joy issued in the bloody sweat. Some think the words do not necessarily imply, that this sweat was blood, or that there was blood in it; only that his sweat, as it came out of his body, and fell on the ground, was so large, and thick, and viscous, that it looked like drops, or clots of blood; but the case rather seems to be this, that the pores of Christ's body were so opened, that along with sweat came out blood, which flowed from him very largely; and as it fell on the ground, he being fallen on his face to the earth, it was so congealed by the cold in the night season, that it became really, as the word signifies, clots of blood upon the earth. The Persic version, different from all others, reads, "his tears, like blood, fell by drops upon the ground". This agony, and bloody sweat of Christ, prove the truth of his human nature; the sweat shows that he had a true and real body, as other men; the anxiety of his mind, that he had a reasonable soul capable of grief and sorrow, as human souls are; and they also prove his being made sin and a curse for us, and his sustaining our sins, and the wrath of God: nor could it be at all unsuitable to him, and unworthy of him, to sweat in this manner, whose blood was to be shed for the sins of his people, and who came by blood and water, and from whom both were to flow; signifying, that both sanctification and justification are from him.
