31 Since it was the day of Preparation, in order to prevent the bodies from remaining on the cross on the sabbath (for that sabbath was a high day), the Jews asked Pilate that their legs might be broken, and that they might be taken away. 32 So the soldiers came and broke the legs of the first, and of the other who had been crucified with him; 33 but when they came to Jesus and saw that he was already dead, they did not break his legs. 34 But one of the soldiers pierced his side with a spear, and at once there came out blood and water. 35 He who saw it has borne witness--his testimony is true, and he knows that he tells the truth--that you also may believe. 36 For these things took place that the scripture might be fulfilled, "Not a bone of him shall be broken." 37 And again another scripture says, "They shall look on him whom they have pierced."

Commentary on John 19:31-37
(Read John 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, Exodus 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.
