John 5:4

First then, as I before said, He causeth defilements of our bodies, and afterwards infirmities of different kinds, to be done away by water. Because God, desiring to bring us nearer to faith in baptism, no longer healeth defilements only, but diseases also. For those figures which came nearer in time to the reality, both as regarded Baptism, and the Passion, and the rest, were plainer than the more ancient; and as the guards near the person of the prince are more splendid than those before, so was it with the types. And "an Angel came down and troubled the water," and endued it with a healing power, that the Jews might learn that much more could the Lord of Angels heal the diseases of the soul. Yet as here it was not simply the nature of the water that healed, (for then this would have always taken place,) but water joined to the operation of the Angel; so in our case, it is not merely the water that worketh, but when it hath received the grace of the Spirit, then it putteth away all our sins. Around this pool "lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water"; but then infirmity was a hindrance to him who desired to be healed, now each hath power to approach, for now it is not an Angel that troubleth, it is the Lord of Angels who worketh all. The sick man cannot now say, "I have no man"; he cannot say, "While I am coming another steppeth down before me"; though the whole world should come, the grace is not spent, the power is not exhausted, but remaineth equally great as it was before. Just as the sun's beams give light every day, yet are not exhausted, nor is their light made less by giving so abundant a supply; so, and much more, the power of the Spirit is in no way lessened by the numbers of those who enjoy it.

"Now an Angel of the Lord descended at certain times into the pool," namely to heal: and he adds the sign of this descent: "And the water was stirred," so that those who could not see the Angel might see the water: and he adds …

Finally, the power of the pool is described, for it healed all physical illnesses in virtue of an angel who came to it; so he says, From time to time an angel of the Lord used to come down into the pool. In certain ways, …

Many thought that the water received a certain divine power from the mere fact that the entrails of the sacrifices were washed in it, and that therefore the Angel also descended upon this water as upon a chosen one and worked miracles. It seems that …

An angel - Yet many undoubtedly thought the whole thing to be purely natural. At certain times - Perhaps at a certain hour of the day, during this paschal week, went down - The Greek word implies that he had ceased going down, before the time of St. John's writing this.

The sermon was Christ's vindication of himself before the sanhedrim, when he was prosecuted as a criminal for healing the man on the sabbath day, in which, 1. He asserts his authority as Messiah, and Mediator between God and man,

How it was called: It was a pool (a pond or bath), which is called in Hebrew, Bethesda--the house of mercy; for therein appeared much of the mercy of God to the sick and diseased. In a world of so much misery as this is, it is well that there are some Bethesdas--houses of mercy (remedies against those maladies), that the scene is not all melancholy.

Secondly, It was a type of the Messiah, who is the fountain opened; and was intended to raise people's expectations of him who is the Sun of righteousness, that arises with healing under his wings.

For an angel went down at a certain season into the pool,....

Angel - “Of the Lord,” is added by AKL, about 20 others, the Ethiopic, Armenian, Slavonic, Vulgate, Anglo-Saxon, and six copies of the Itala: Cyril and Ambrose have also this reading. If this reading be genuine, and the authorities which support it are both ancient and respectable, it destroys Dr. Hammond’s conjecture, that, by the angel, a messenger only, sent from the Sanhedrin, is meant, and that these cures were all performed in a natural way.

We have heard of many waters having a medicinal virtue; but what water was ever known to cure instantaneously a single disease? And who ever heard of any water curing all, even the most diverse diseases--"blind, halt, withered"--alike?

We have in this passage one of the few miracles of Christ, which John records. Like every other miracle in this Gospel, it is described with great minuteness and particularity. And like more than one other miracle it leads on to a discourse full of singularly deep instruction. We are taught, for one thing, in this passage, what misery sin has brought into the world. We read of a man who had been ill for no less than thirty-eight years! For thirty-eight weary summers and winters he had endured pain and infirmity.

We have in this passage one of the few miracles of Christ, which John records. Like every other miracle in this Gospel, it is described with great minuteness and particularity. And like more than one other miracle it leads on to a discourse full of singularly deep instruction. We are taught, for one thing, in this passage, what misery sin has brought into the world. We read of a man who had been ill for no less than thirty-eight years! For thirty-eight weary summers and winters he had endured pain and infirmity. He had seen others healed at the waters of Bethesda, and going to their homes rejoicing. But for him there had been no healing. Friendless, helpless, and hopeless, he lay near the wonder-working waters, but derived no benefit from them. Year after year passed away, and left him still uncured. No relief or change for the better seemed likely to come, except from the grave. When we read of cases of sickness like this, we should remember how deeply we ought to hate sin! Sin was the original root, and cause, and fountain of every disease in the world. God did not create man to be full of aches, and pains, and infirmities. These things are the fruits of the Fall. There would have been no sickness, if there had been no sin. No greater proof can be shown of man's inbred unbelief, than his carelessness about sin. "Fools," says the wise man, "make a mock at sin." (Pro. 14:9.) Thousands delight in things which are explicitly evil, and run greedily after that which is downright poison. They love that which God abhors, and dislike that which God loves. They are like the madman, who loves his enemies and hates his friends. Their eyes are blinded. Surely if men would only look at hospitals and infirmaries, and think what havoc sin has made on this earth, they would never take pleasure in sin as they do. Well may we be told to pray for the coming of God's kingdom!

THE scene of this miracle was Bethesda, a pool, according to the Evangelist, adjoining the sheep market, or near the sheep gate—the place through which, I suppose, the cattle consumed by the inhabitants of Jerusalem would be driven— and the pool where, perhaps, the sheep intended for sale to the offerers in the temple were washed. So common was sickness in the days of the Savior that the infirmities of men intruded upon the place which had been allotted to cattle!

So common was sickness in the days of the Savior that the infirmities of men intruded upon the place which had been allotted to cattle! And the place where sheep had been washed became the spot where sick folk congregated in great multitudes, longing for a cure. We do not hear that anyone remonstrated at the intrusion, or that public opinion was shocked. The needs of mankind must override all considerations of taste. A hospital must have preference over a sheep market. This day you have another case in point. If the physical infirmities of Jerusalem intruded into the sheep market, I shall ask no excuse if, on these Sundays, the spiritual sickness of London should demand that this spacious place, which has up to now been given up to the lowing of cattle and to the bleating of sheep, should be consecrated to the preaching of the Gospel—to the manifestation of the healing virtue of Christ Jesus among the spiritually sick! This day there is, by the sheep market, a pool, and impotent folk are here in exceeding great multitudes. We might never have heard of Bethesda if an august visitor had not condescended to honor it with His Presence—Jesus, the Son of God, walked in the five porches by the pool. It was the place where we might expect to meet Him, for where should the Great Physician be found if not in the place where the sick are gathered? Here was work for Jesus' healing hand and restoring word.

An angel - It is not affirmed that the angel did this “visibly,” or that they saw him do it. They judged by the “effect,” and when they saw the waters agitated, they concluded that they had healing properties, and descended to them. The Jews were in the habit of attributing all favors to the ministry of the angels of God, Gen 19:15; Heb 1:14; Mat 4:11; Mat 18:10; Luk 16:22; Act 7:53; Gal 3:19; Act 12:11. This fountain, it seems, had strong medicinal properties. Like many other waters, it had the property of healing certain diseases that were incurable by any other means. Thus the waters of Bath, of Saratoga, etc., are found to be highly medicinal, and to heal diseases that are otherwise incurable. In the case of the waters of Bethesda there does not appear to have been anything “miraculous,” but the waters seem to have been endued with strong medicinal properties, especially after a periodical agitation. All that is special about them in the record is that this was produced by the ministry of an angel. This was in accordance with the common sentiment of the Jews, the common doctrine of the Bible, and the belief of the sacred writers. Nor can it be shown to be absurd or improbable that such blessings should be imparted to man by the ministry of an angel. There is no more absurdity in the belief that a pure spirit or holy “angel” should aid man, than that a physician or a parent should; and no more absurdity in supposing that the healing properties of such a fountain should be produced by his aid, than that any other blessing should be, Heb 1:12.
