John 19:31-35

31It was the day of Preparation, and the next day was a High Sabbath. In order that the bodies would not remain on the cross during the Sabbath, the Jews asked Pilate to have the legs broken and the bodies removed. 32So the soldiers came and broke the legs of the first man who had been crucified with Jesus, and those of the other.

33But when they came to Jesus and saw that He was already dead, they did not break His legs. 34Instead, one of the soldiers pierced His side with a spear, and immediately blood and water flowed out. 35The one who saw it has testified to this, and his testimony is true. He knows that he is telling the truth, so that you also may believe.
