The Jews therefore (because it was the preparation) that the bodies should not remain on the cross on the sabbath day (for that sabbath-day was an high day) besought Pilate that their legs might be broken, and that they might be taken away. See Deut. xxi22. This was done, in order that they might not pollute and make gloomy this most solemn festival, by the horror of their sufferings, as St. Augustine says. It was necessary therefore that they should die and be buried before sunset, at which time the sabbath began. "That," as Theophylact says, "the sun might not set on their sufferings."
For this was the sabbath within the octave of the Passover, and for this reason a more solemn day than other sabbaths.
Their legs were to be broken with the strong blows of a mallet or iron Baruch , to make them die the sooner, from the intensity of the pain, or the loss of blood, or because the vital force resides in the knees and legs. (See Pliny, N. H. xi45.)
But why did they not pierce their hearts with a spear or sword, which would have been an easier and a quicker death? They preferred to break the legs of criminals, in order to increase their sufferings, as even now notorious criminals are put on the rack. Probably the Jews wished to do this to Christ, out of bitter hatred, and Baronius thinks that they gave Him vinegar to keep Him alive for this further torture. But He was already dead, not because He dreaded this further suffering, but on account of the mystery (of which more presently), but also because His strength was worn out by all He had already undergone. (See Lipsius, de Cruce, ii14.)
These Jews seemed to urge their being taken down from the cross, not so much from any regard for the sabbath, as from dread, shame, and consciousness of guilt. For they saw the sun darkened, the veil of the temple rent, the earthquake, &c, all which condemned their treatment of Christ. And they therefore feared either that God would punish them, or the people rise up against them as the murderers of Christ. They ordered Him therefore to be taken down from His seat of triumph, and to be buried. See F. Lucas.
