(34) But one of the soldiers with a spear pierced his side.--They had seen that He was dead, and therefore did not break the legs. To cause death was not, then, the object in piercing the side; and yet it may have seemed to make death doubly sure. The word rendered "pierced" occurs nowhere else in the New Testament, but it is certain, from John 20:27, that the act caused a deep wound, and that the point of the lance therefore penetrated to the interior organs of the body. If the soldier stood before the cross, this wound would naturally be in the left side.

And forthwith came there out blood and water.--"Various physiological explanations have been given of this fact, such as--(1) that the lance pierced the pericardium, which contained a small quantity of watery lymph, which immediately flowed out; and also the heart, from which the blood flowed, the actual death taking place at this moment; (2) that the physical death of Christ resulted from rupture of the heart, and that the cavities of the heart and the surrounding-vessels contained a watery fluid; (3) that decomposition of the blood in the corpse had taken place, the solid matter being separated from the fluid, so that it would appear to be blood mixed with water. (Comp. Notes on 1John 5:5-6.)

Whatever solution we adopt, it is clear that death had taken place some time previously (John 19:30), and that, while we cannot say which physical explanation is the true one, there is within the region of natural occurrences quite sufficient to account for the impression on the mind of St. John which he records here. We have to think of the disciple whom Jesus loved looking at the crucified and pierced body of his Lord, and remembering the picture in later years, and telling that there flowed from that pierced side both blood and water.

19:31-37 A trial was made whether Jesus was dead. He died in less time than persons crucified commonly did. It showed that he had laid down his life of himself. The spear broke up the very fountains of life; no human body could survive such a wound. But its being so solemnly attested, shows there was something peculiar in it. The blood and water that flowed out, signified those two great benefits which all believers partake of through Christ, justification and sanctification; blood for atonement, water for purification. They both flow from the pierced side of our Redeemer. To Christ crucified we owe merit for our justification, and Spirit and grace for our sanctification. Let this silence the fears of weak Christians, and encourage their hopes; there came both water and blood out of Jesus' pierced side, both to justify and sanctify them. The Scripture was fulfilled, in Pilate's not allowing his legs to be broken, Ps 34:20. There was a type of this in the paschal lamb, Ex 12:46. May we ever look to Him, whom, by our sins, we have ignorantly and heedlessly pierced, nay, sometimes against convictions and mercies; and who shed from his wounded side both water and blood, that we might be justified and sanctified in his name.But one of the soldiers,.... Whose name some pretend to say was Longinns, and so called from the spear with which he pierced Christ:

with a spear pierced his side; his left side, where the heart lies; though the painters make this wound on the right, and the Arabic version of Erpenius, as cited by Dr. Lightfoot, adds the word "right" to make the miracle the greater: this the soldier did, partly out of spite to Christ, and partly to know whether he was really dead; and which was so ordered by divine providence, that it might beyond all doubt appear that he really died, and was not taken down alive from the cross; so that there might be no room to call in question the truth of his resurrection, when he should appear alive again:

and forthwith came there out blood and water; this is accounted for in a natural way by the piercing of the "pericardium", which contains a small quantity of water about the heart, and which being pierced, a person, if alive, must inevitably die; but it seems rather to be something supernatural, from the asseverations the evangelist makes. This water and blood some make to signify baptism and the Lord's supper, which are both of Christ's appointing, and spring from him, and refer to his sufferings and death; rather they signify the blessings of sanctification and justification, the grace of the one being represented by water, as it frequently is in the Old and New Testament, and the other by blood, and both from Christ: that Christ was the antitype of the rock in the wilderness, the apostle assures us, in 1 Corinthians 10:4 and if the Jews are to be believed, he was so in this instance; Jonathan ben Uzziel, in his Targum on Numbers 20:11 says that

"Moses smote the rock twice, at the first time , "blood dropped out": and at the second time abundance of waters flowed out.''

The same is affirmed by others (h) elsewhere in much the same words and order.
