John 19:34-37

Yet one of the soldiers pierced His side with a spear, and immediately blood and water came out. And he who has seen has testified, and his testimony is true; and he knows that he is telling the truth, so that you also may believe. For these things took place so that the Scripture would be fulfilled: “NOT A BONE OF HIM SHALL BE BROKEN.” And again another Scripture says, “THEY WILL LOOK AT HIM WHOM THEY PIERCED.”
