The Jews therefore, because it was the preparation, that the bodies should not remain upon the cross on the sabbath day, (for that sabbath day was a high day,) besought Pilate that their legs might be broken, and that they might be taken away.

Augustine of Hippo
AD 430
Not in order to take away the legs, butto cause death, that they might be taken down from the cross, and the feast day not be defiled by the sight of such horrid torments.
The Evangelist has expressed himself cautiously; not struck, or wounded, but opened His side: whereby was opened the gate of life, from whence the sacraments of the Church flowed, without which we cannot enter into that life which is the true life: And forthwith camethereout blood and water. That blood was shed for the remission of sins, that water tempers the cup of salvation. This it was which was prefigured when Noah was commanded to make adoor in the side of the ark, by which the animals that were not to perish by the deluge entered; which animals prefigured the Church. To shadow forth this, the woman was made out of the side of the sleeping man; for this second Adam bowed His head, and slept on the cross, that out of that which came therefrom, there might be formed a wife for Him. O death, by which the dead are quickened, what can be purer than that blood, what more salutary than that wound! .
He that saw it knows; let him that saw not believe his testimony. He gives testimonies from the Scriptures to each of these two things he relates. After, they brake not His legs, He adds, For these things were done, that the Scripture should be fulfilled, A bone of Him shall not be broken, a commandment which applied to the sacrifice of the paschal lamb under the old law, which sacrifice foreshadowed our Lord’s. Also after, One of the soldiers with a spear opened His side, then follows another Scripture testimony; And again another Scripture said, They shall look on Him whom they pierced, a prophecy which implies that Christ will come in the very flesh in which He was crucified.
