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 an high day,) besought Pilate that their legs might be broken, and that they might be taken away.
Since it was about to be a special day, the Jews asked Pilate to break the legs of the crucified people and remove them from the crosses before the Sabbath began, so their bodies wouldn't be there on that important day.
